Abstract :
In this paper, we present a motion error model for a Frequency-Modulated Continuous-Wave (FMCW) SAR system, and analyze the characteristics of the intrapulse motion error. Furthermore, we develop an effective compensation approach to handle motion errors based on our previous result. Finally, we validate the formulated signal model and compensation method by using simulated FMCW SAR data.
