Research on MIMO Radar Based on Orthogonal Signal in the Present of Non-Ideal Factor

摘要

Non-ideal factors of transmitting signal are known as a kind of restriction to the performance of radar,especially the ability of finding the weak target. In this paper, the performance of MIMO radar in the aspect of weak targetdetection is researched. Firstly, the theory model of MIMO signal is presented. And then, a simulation system based onorthogonal signal is established. In this simulation platform, the performance of MIMO radar and phased array radar arestudied. Simulation results show that for the same receiver limiting factor, the statistical error probability of MIMO radaris much lower than traditional phased array mode.
