Abstract:

MIMO technology having been applied, the multichannel  radar can extend the array aperture and improve the performance of resolution.This paper shows that an MIMO radar may be simulated through the time-sharing motions of a single transmitter and a single receiver,and an MIMO radar simulated experimental system is constructed by a single transmitter and a single receiver. The constructed principle and measures are given Finally, the experiment using real array and equivalent array shows the array virtual aperture is expanded, and the resolution of both imaging and DOA estimation is improved.
