A novel motion compensation approach for highly-manoeuvring platform SAR imagery

This paper presents a novel motion compensation approach for highly-manoeuvring platform SAR imagery. Different from the conventional motion compensation approaches, the predetermined accuracy of the measurement system (e.g. INS/GPS system) is adequately utilized to effectively improve the computational efficiency of estimation on residual Doppler rate. Based on the estimated residual Doppler rate, the motion induced phase error is subsequently compensated to achieve a well-focused image. Simulation is presented to validate the effectiveness of the proposed method.
