Abstract

An imaging approach based on the Double Frequency Slope (DFS) waveform in multiple-input and multiple-output (MIMO) synthetic aperture radar (SAR) is presented in this paper. Firstly the DFS waveform’s range-Doppler domain’s features after in range direction is analyzed based on principle of stationary phase. Then the phase compensation in the range-Doppler domain is given. Combined with phase characteristic of the multi-antenna, the imaging of MIMO-SAR is achieved. The influence is eliminated because of the double frequency slope, and the sidelobe level in the range direction are reduced by this method. Finally simulation experiments of MIMO-SAR show the correctness and effectiveness of this approach.
