摘要：
The problems of target's distance and angle two-dimensional parameters estimation methods in frequency diverse array multiple input and multiple output (MIMO) radar were studied under non-time-varying and time-varying steering vectors, respectively. Under the circumstance of non-time-varying steering vectors, a spectrum estimation method based on choking estimation of signal parameters via rotational invariance techniques(ESPRIT) modified algorithm was put forward, which could achieve parameter automatic pair with guaranteed estimation accuracy at the mean time. Under the circumstance of time-varying steering vectors, the influence on spectrum estimation was analyzed, thus, a divisional average estimation strategy wasput forward and the problem of parameter estimation under time-varying condition was well solved. Theory analysis and simulation results show that the proposed algorithm can effectively estimate thethe range and angle parameter of frequency diverse array MIMO radar and perform better than other dimensionality reduction algorithms in estimated accuracy as well as parameter pairing. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology.
