Abstract

This paper presents a modified algorithm for the estimation of linear frequency modulated signal of synthetic aperture radar (SAR) raw data, which is based on phase unwrapping and polynomial fitting. On the mathematical model of SAR raw data, the paper analyzes the Doppler parameters estimation of the key problem to generate high quality SAR images, considering the raw signal is embedded in additive noise. The results of simulation show that the new method is reasonable and can make blind processing SAR raw data, and improve images quality
