Abstract

Abstract: Space-borne SAR flies at high altitude, moves fast, has large radar detecting range and wide measuring swath, and its traveling orbit deviates from on ideal circle, so it is complex for digital signal processing technique to obtain SAR imagery. According to th2 properti3S mentioned above, the target return wave modol of spacer-borne SAR, azimuth processing principle and method in the imaging, and multi-look processing are discussed in this paper.

Key words: synthetic aperture radar, radar imaging, multi-look processing
