Remote sensing instruments are of two primary types—active and passive. Active sensors, provide their own source of energy to illuminate the objects they observe. An active sensor emits radiation in the direction of the target to be investigated. The sensor then detects and measures the radiation that is reflected or back scattered from the target. Passive sensors, on the other hand, detect natural energy (radiation) that is emitted or reflected by the object or scene being observed. Reflected sunlight is the most common source of radiation measured by passive sensors.
Active Sensors

The majority of active sensors operate in the microwave portion of the electromagnetic spectrum, which makes them able to penetrate the atmosphere under most conditions. An active technique views the target from either end of a baseline of known length. The change in apparent view direction (parallax) is related to the absolute distance between the instrument and target.

    Laser altimeter — An instrument that uses a lidar to measure the height of the platform (spacecraft or aircraft ) above the surface. The height of the platform with respect to the mean Earth’s surface is used to determine the topography of the underlying surface.
    Lidar—A light detection and ranging sensor that uses a laser (light amplification by stimulated emission of radiation) radar to transmit a light pulse and a receiver with sensitive detectors to measure the back scattered or reflected light. Distance to the object is determined by recording the time between transmitted and back scattered pulses and by using the speed of light to calculate the distance traveled.
    Radar—An active radio detection and ranging sensor that provides its own source of electromagnetic energy. An active radar sensor, whether airborne or space borne, emits microwave radiation in a series of pulses from an antenna. When the energy reaches the target, some of the energy is reflected back toward the sensor. This back scattered microwave radiation is detected, measured, and timed. The time required for the energy to travel to the target and return back to the sensor determines the distance or range to the target. By recording the range and magnitude of the energy reflected from all targets as the system passes by, a two-dimensional image of the surface can be produced.
    Ranging Instrument—A device that measures the distance between the instrument and a target object. Radars and altimeters work by determining the time a transmitted pulse (microwaves or light) takes to reflect from a target and return to the instrument. Another technique employs identical microwave instruments on a pair of platforms . Signals are transmitted from each instrument to the other, with the distance between the two determined from the difference between the received signal phase and transmitted (reference) phase. These are examples of active techniques. An active technique views the target from either end of a baseline of known length. The change in apparent view direction (parallax) is related to the absolute distance between the instrument and target. 
Scatterometer—A high-frequency microwave radar designed specifically to measure back scattered radiation. Over ocean surfaces, measurements of back scattered radiation in the microwave spectral region can be used to derive maps of surface wind speed and direction. 
Sounder—An instrument that measures vertical distribution of precipitation and other atmospheric characteristics such as temperature, humidity, and cloud composition .

passive sensors
Passive sensors include various types of radiometers and spectrometers. The most passive systems used in remote sensing applications operating in the visible, infrared, infrared, thermal and microwave portion of the electromagnetic spectrum. passive remote sensors include:

    
Accelerometer - an instrument that measures the acceleration (change in velocity per unit time). There are two common types of accelerometers. One measure of  translational acceleration (linear motion changes in one or more dimensions), and other measures the angle acceleration (change in rotation rate per unit time).
    
Hyperspectral radiometer - advanced multi spectral sensor that can detect hundreds of very narrow spectral bands throughout the visible, near-infrared and mid-infrared of the electromagnetic spectrum. very high spectral resolution sensor facilitates the discrimination between different targets based on their spectral response in each band is narrow.
    
Imaging radiometer - scanning radiometer that has the ability to provide a two-dimensional array of pixels where the image can be produced. Scanning can be done mechanically or electronically using the detector array. can scan elbow elbow of a high rise building in order to avoid the slope in mechanical physics.
    
Radiometer - a device that quantitatively measures the intensity of electromagnetic radiation in multiple bands in the spectrum. Typically, a radiometer are further identified by a part of the spectrum include; for example, visible, infrared, or microwave.
    
Sounder - instruments that measure the vertical distribution of atmospheric parameters such as temperature, pressure, and composition of multi spectral information.
    
Spectrometer - a device designed to detect, measure, and analyze the spectral content of electromagnetic radiation incident. Conventional imaging spectrometer using a grating or prism to disperse radiation for spectral discrimination.
    
Spectroradiometer - radiometer that measures the intensity of radiation at some wavelength bands (ie, multi spectral). Many times the high resolution spectral band, which is designed to remotely sense a certain geophysical parameters .

How to Make a Strong Foundation House and Sturdy and glance to Process peek Skyscraper AMNIMARJESLOW AL DO FOUR DO AL ONE LJBUSAF thankyume orbit



The foundation of the house is the most basic part is very important. The foundation must be made sturdy Darena position as a determinant of the robustness of the building. That is, if the foundation is made carelessly, then the building will be generated also will not be established. Meanwhile, if the foundation is made sturdy and strong, the building will be standing with kekokohannya own. The impact of the good, the house is built to be durable and resistant to shocks. If you are confused with how to create a foundation or a good home base and strong, this time I summarize some way, the following techniques may be used. Check out the full review and detailed below.
 
Here's how to make the foundation strong and sturdy house 



Begini Cara Membuat Pondasi Rumah yang Kuat dan Kokoh Begini Cara Membuat Pondasi Rumah yang Kuat dan Kokoh 

The first technique: Mechanical stone

The first technique is to make use stone foundation. In this case, stone mixed with cement and sand volume ratio is 1 than 4. Make sure that the mixture of all the ingredients can be fitted and can accommodate a building to be erected.
The second technique: Concrete Systems

This second technique is a technique that uses a system of reinforced concrete. In this technique, you can mix the cement, gravel, and sand. Cement volume ratio: gravel, sand is 1: 3: 2. Once the mixture is ready, you can incorporate iron reinforcement into it. You can choose the first technique or a second technique to make the best house foundation. The next technique is a technique which can amplify the first and second techniques



The third technique: Flatten
The size of the slope should be calculated and realized in the form of foundation. The aim is that the foundation created to support the weight properly and not skewed. If the building tilted, then the buildings standing on it could be so easily collapse. For that, it needs to be made flat and straight 180 degrees. To realize this needs to be made sloop. Sloop made from a cast iron reinforcement, then mixed with cement, gravel, and sand. Comparison cement: gravel, sand is 1: 3: 2.The fourth technique: Installation of plastic
Installation of plastic made to strengthen the foundation. Polyfiled plastic is plastic in question here. Typically, this plastic is used as tents for stalls on the roadside, belonging to street vendors. These plastics are used as a coaster gravel. It's easy, polyfiled title, put the gravel thickness of 15 to 20 cm above it. Flatten out at once and pressing so as not to move. Continue with the good foundation construction technique of the first, nor the second technique.
Some of the above can be done to create the foundation for a strong and solid home. 



Know Multiple Types of Foundation House  


Regardless of the type and shape of the house, a house foundation is the most important element in the structure of the house. in other words, the base of the structure which has an important function, namely to withstand heavy loads of all components on it. So basically it is a good building for the home, be it high-rise buildings or small, its main strength lies in its foundation. Given the fragility or strength of a building depends on the solid foundation of the house, the foundation itself will need to consider the amount of construction that will be above the foundation. These considerations are in addition to ensuring the strength of the foundation of buildings on it, and save the cost construction of the foundation itself.
Similarly, the interior and exterior needs to touch by adjusting the room as the desired model homes, as well as the foundation of the house also have to adjust to the shape of the house. In short, any kind of home generally use different types of house foundation depends on the size and structure of the house to be built. So in this case adjust the type of foundation with the character of the house needs to be done to ensure the strength of the house is built.

The house foundation types
In general, the type of foundation is divided into two distinct groups, namely the basic foundation of deep and shallow. Here is the definition of each type of foundation:foundations In
The foundation is usually used for the construction of houses or buildings with large load capacity, eg house consisting of several floors, turrets, towers, apartments, hotels, high-rise buildings and the like. This foundation is divided into three types: Piles foundation, and the foundation Pile foundation Pile Drill Strous.Shallow foundations
Shallow foundation is usually used for the construction of homes that do not use a load that is too large, for example house 1 floor, shops, kiosks, guard posts, police stations, or other small buildings. There are several types of foundation include shallow foundation categories, namely: Foundations Rollag (brick), foundation pile (foot plate), Terucuk Bamboo Foundation, Foundation Stone Masonry and Chicken Claw Foundation or parallel bus foundation .
In addition to the above two types of foundation of the house, there are many more types of foundation architect innovation results. The purpose of the development of the foundation structure is actually a form of business to create a foundation structure in cost savings, but other than that this development objective is to get a strong foundation structure to support the beauty of the building.Tips on Creating a foundation structure for the Best Results
To get the basic structure of a good and solid home, it takes planning and implementation through certain stages. And to get the best basis, we see tips on making the structure of its solid foundations following:Tips To Make Your First Base Structure
We must ensure that the foundation soil conditions will create a good foundation. If there are certain particles that make the soil less good then the necessary corrective soil structure before making foundation in the ground area.Tips to Make Second Base Structure
Foundation plan should have done earlier. This is to ensure that no errors occur in the future so do not need to do the demolition. In addition, careful planning will produce a strong foundation and saving houses in terms of funding.  



Tips to Make Third Base Structure

Adjusting the foundation structure with the building structure to be built.
Tips to Make the Fourth Base Structure

Choose a good quality material. Quality materials are used generally affect the strength and durability of the house foundation later. For the selection of materials for selectively including cement, sand, rocks, and other ingredients to create a foundation.

Tips on Creating a foundation structure of the Fifth

Determining the appropriate working methods. This means that determining the appropriate time to make a house foundation. Ideally the house foundation made during the dry season when rainfall has the potential minimal / low rainfall. This is to keep the foundation remains in dry conditions although it sometimes takes a splash of water.
