Abstract For the urgent need of the waveform for Multiple-transit and Multiple-receive SAR, three kinds of waveforms are researched and compared, which are the representative waveforms for the Multiple-transit and Multiple-receive SAR, and evaluate the practicality by simulating the distributing target. On this base, the waveform separation and energy separation rules for echoes of Multiple-transit and Multiple-receive SAR are proposed. The phase compensates and channel responses for the Double-transit and Multiple-receive SAR which uses space-time coding as waveform are also given. It is proved that this system has predominance in improving SNR than Single-transit and Single-receive SAR.
