Abstract

Stepped-frequency subpulse signals are widely used to obtain ultra-high range resolution. The stepped-frequency subpulse signals can be combined to one single signal with high bandwidth by using synthetic bandwidth methods. In practical SAR imaging motion error and the time delay of echo signal must be considered before applying the available synthetic bandwidth methods. This paper presents a method in which motion compensation and compensation in Doppler domain are integrated with time domain synthetic bandwidth method in order to get high quality SAR image
