Abstract

To overcome the inherent conflict between azimuth resolution and wide swath in conventional synthetic aperture radar (SAR) systems, the concept of raster scan SAR (RS-SAR) is proposed in this letter, where wide swath observation is realized by slant beam scanning and effective reception of echo data is achieved by varying the pulse repetition frequency. Details of the RS-SAR are provided, and its significantly improved performance is demonstrated by an example system based on several derived key performance indicators.
