Advanced Microwave Active & Passive Remote Sensing Application and Its Utilization
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
Microwave sensing circumscribes both active and passive forms of remote sensing. Long wavelengths, match up to the visible and infrared. Its radiation can penetrate through haze, cloud cover and dust. Longer wavelengths are not susceptible to atmospheric scattering which affects shorter optical wavelengths all but the heaviest rainfall. Data can be collected at any time because microwave allows detection of microwave energy under almost all environmental conditions. Passive microwave sensing is similar in concept to thermal remote sensing. All objects produce together microwave energy of a small amount. A passive microwave sensor identifies the naturally emitted microwave energy within its ground of view. This secretive energy is related to the temperature and moisture properties of the emitting object or surface. Passive microwave sensors are normally radiometers or scanners and operate systems, I FOCUS ON imaging radars. As with passive microwave sensing, a most significant advantage of radar is the ability of the radiation to penetrate through cloud cover and most weather conditions. It can also be worn to image the surface at every time, day or night. These are the two primary advantages of radar: all-weather and day or night imaging discussed previously except that an antenna is used to detect and record the microwave energy. In this paper different Applications of passive microwave remote sensing consist of oceanography, hydrology and meteorology by come transverse lying through the atmosphere.
