MIMO雷达波达方向估计的性能分析

Abstract

Abstract:

The Cramer-Rao Bound(CRB) for MIMO radar DOA estimation with co-located arrays in a single target scenario is derived, which shows that CRB depends on both the steering vectors of transmit/receive arrays and the correlation matrix of transmitted waveforms. Compared with traditional phased array radar, MIMO radar has a better DOA estimation performance for most angles. CRB can be further reduced by increasing the spaces between transmit array elements in the MIMO radar system so that MIMO radar can obtain a much better DOA estimation performance than phased array radar. Simulation results validate above conclusions.

Key words: MIMO radar, DOA estimation, Cramer-Rao bound, correlation matrix
