Microwave remote sensing systems are classified into two groups: passive and active.
3.1 Principles of Microwave Remote Sensing Microwave remote sensing, using microwave radiation using wavelengths from about one centimeter to a few tens of centimeters enables observation in all weather conditions without any restriction by cloud or rain. These systems are generally characterized by relatively low spatial resolutions. Share. Google Earth has further made access to high spatial resolution remote sensing data available to non-experts with great ease.
If you have any questions about copyright issues, please report us to resolve them. The importance of remote sensing methods and techniques for different engineering branches has been well known for several decades, even before the deployment of the first satellite sensor for Earth observation.

Bhattacharya 6 Advantages compared to optical remote sensing All weather capability (small sensitivity of clouds, light rain) Day and night operation (independence of sun illumination) No effects of atmospheric constituents (multitemporal analysis) Sensitivity to dielectric properties (water content , biomass, ice)
Presently, remote sensing datasets available from various earth orbiting satellites are being used extensively in various domains including in civil engineering, water resources, earth sciences, transportation engineering, navigation etc. In fact, objects emit energy at the microwave frequencies, although sometimes in an extremely small amount.
Passive systems collect the radiation that is naturally emitted by the observed surface.
