Joint 2D Hybrid MIMO Phased-Array and Nested Array for Increased Apertures
Abstract— In this paper, a receive array design method based on 2D nested array for two dimensional
Hybrid MIMO phased-array radar is proposed. It can offers more apertures by forming difference coarray,
which will defeat the apertures sacrifice brought by the two dimensional Hybrid MIMO phased-array radar as
compared to the traditional MIMO radar. Spatial smoothing will also used to form the subspace based DOA
estimation like Unitary ESPRIT. Numerical simulation will validate the proposed approach.
Index Terms— 2D Hybrid MIMO phased-array radar, 2D Nested array ， direction of arrival (DOA)
estimation, Unitary ESPRIT.
