5. Conclusion
The Microwaves have unique applications in remote sensing.
Also along with optical and infrared they provide
complimentary and supplementary information about the targets.
The Remote Sensing of PLANETS also is possible using
microwave sensors. As can be seen the hitherto unknown areas
in PLANETS can be explored by microwaves. Thus the
microwave remote sensing will play a major role in exploration
of EARTH as well as PLANETS.
