The previous discussions of this A.S.I. of target scattering and effects of the atmosphere upon microwave propagation are extended to the problem of imaging by synthetic aperture radar (SAR). The foundation for discussion of SAR system performance has been given by Corless [1].

Radar is an active microwave remote sensing system, first developed during the Second World War with the purpose of evaluating distances between targets (aircrafts, ships, etc.) and the antenna used to send and receive an Electromagnetic (EM) pulse (Woodhouse 2006; Brown 1999).

Some of the most striking images of the earth’s surface have been made from aircraft in level flight using radar in a sophisticated modality. The foliage of trees is stripped away and the ridges and gullies of the hard surface are shown in stark relief.

High angular resolution radar imagery can be obtained using conventional non-coherent radar systems by employing a large antenna or operating at a short wavelength. Airborne platforms, however, impose severe physical limitations on the size of the antenna which can be used and still maintain acceptable flight characteristics of the aircraft. The use of

The general theory of side-looking synthetic aperture radar systems is developed. A simple circuit-theory model is developed; the geometry of the system determines the nature of the prefilter and the receiver (or processor) is the postfilter. The complex distributed reflectivity density appears as the input, and receiver noise is first considered as ...
