Abstract

Unmanned aerial vehicle multiple-input multiple-output synthetic aperture radar (MIMO-SAR) can realize high resolution imaging by its predominance of the multichannel spatial parallel sampling, but the inevitable problem of motion compensation must to be resolved. So the imaging method of unmanned aerial vehicle MIMO-SAR based on motion compensation was proposed. The motion error was divided into two parts by analyzing the motion model of MIMO-SAR system, and then the motion error of the echo data was corrected by two steps of compensation. Finally, the effectiveness of the proposed method was proved by the simulation results.

Key words： MIMO-SAR; motion error; unmanned aerial vehicle; range-Doppler algorithm
