Microwave sensors are unique in their capability to provide timely information under conditions when other sensors are rendered inoperable by the weather. But, resolution with microwave sensors normally is poorer than with sensors operating in the optical and infrared region. Thus, a radar in which a synthetically long apparent or effective aperture is using to increase a resolution.
This paper describes the fundamentals and effective application of the synthetic aperture radar (SAR) which is one of the promissing microwave sensor for earth observation.
