The Analysis of Waveform Choice for Multiple-Transit and Multiple-Receive Space-Borne SAR

摘要

摘要: 针对多发多收SAR系统发射波形研究的迫切需要，该文对3种具有代表性的可能作为多发多收SAR系统发射波形的信号进行了研究和比较，通过对分布目标的仿真验证其实用性。并在此基础上提出了多发多收SAR系统回波的波形分离和能量分离的原则，推导了应用空时编码的相位补偿量和两发多收实用化系统的通道响应，论证了其相对于单发单收SAR系统在提高信噪比方面的优势。

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.
