Improved Joint DOD and DOA Estimation for MIMO Array With Velocity Receive Sensors

This letter discusses the problem of direction of departure (DOD) and direction of arrival (DOA) estimation for multi-input multi-output (MIMO) array system, which is configured with multiple transmit sensors and multiple velocity receive sensors. Reference presented a successive multiple signal classification MUSIC algorithm for joint estimation of DOD and DOA for the bistatic MIMO array system with velocity receive sensors. In this letter, we propose an improved joint DOD and DOA estimation algorithm, which has much better angle estimation performance and lower complexity than the successive MUSIC algorithm in . Furthermore, the proposed algorithm can be suitable for irregular array geometry, obtain automatically paired 2-D angle estimation, and avoid 2-D searching. Simulation results verify the usefulness of the proposed algorithm.
