Abstract
This article investigates synthetic aperture radar (SAR) image quality as a function of received signal-to-noise ratio, multiple looks or diversity averaging of “speckle,” contrast, and resolution. Theoretical and simulation results are presented. The data are useful for tradeoff analyses in the design of the SAR, the image processing system, and the telemetry system. Photographs have been made to show the effect of the above-mentioned parameters. The general conclusion is that diversity averaging produces an image far superior to that obtained via equivalent receiver signal-to-noise improvement.
