一种适用于MIMO雷达的低复杂度二维DOA估计方法
A Low Complexity 2-D DOA Estimation Method for MIMO Radar
摘要
Abstract
The virtual array of multiple-input multiple-output (MIMO) radar could be divided into multiple subarrays with the same geometric configuration but different locations. Based on the rotation invariance property of these subarrays,a low complexity 2-D DOA estimation method for MIMO radar is presented in this paper. For each target,multiple 2-D DOA estimates are obtained by applying a pre-projection based ESPRIT algorithm to different subarray combinations. Then, the estimates of each target are fused via Kalman filtering to improve the estimation accuracy. Moreover, sample multiplexing based on the symmetric data structure of MIMO radar further improves the estimation accuracy. Numerical examples demonstrate the effectiveness of the proposed method.关键词
