Abstract

Abstract

Taking Rayleigh model as an example, this paper studies a correction method for Synthetic Aperture Radar (SAR) analog-to-digital converter saturation based on power compensation and extends it to Weibull model. Then it analyzes the applicability of the Weibull model correction method and verifies it by the Radarsat SAR data.
