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.
