摘要

摘要: 该文对单发射多接收(SIMO)和多发射多接收(MIMO)系统进行了研究，对多个孔径天线依次发射，多个孔径同时接收和多个孔径天线同时发射接收等工作方式进行了理论推导，通过采用虚拟孔径相位校正的方法，实现单发多收信号叠加成像。对多个频率同时发射方式，通过采用子带合成和虚拟孔径相位校正的方法，实现多个接收信号的叠加。并对虚拟孔径相位校正的方法进行了点目标仿真。为SAR新体制应用提供了潜在的处理方法。

Abstract: This paper investigates on SAR system that is constituted from Single-Input Multiple-Output (SIMO) or Multiple-Input Multiple-Output (MIMO), and researches the working mode of transmitting one by one or transmitting in same time with multiple transmitters and multiple receivers. Through virtual aperture phase correction, SIMO signal iterations and image algorithms with multiple receivers are performed. Through sub band synthesis and virtual aperture phase correction, MIMO signal iterations and image algorithms are processed with the similar ways; and some simulations of virtual aperture phase correction with three point objects images are provided. The algorithms will be potential to new MIMO-SAR system.
