MIMO 雷达迭代降维稳健波束形成方法
Iterative dimension-reduced robust adaptive beamformer for MIMO radar
摘要
Abstract
Aiming at the transmitted and received steering vectors mismatch problem , an iterative dimension-reducing robust adaptive beamformer for MIMO radar is presented . The General Linear Combined( GLC) method is applied in MIMO radar to obtain the enhanced covariance matrix estimation , and the transmitted and received steering vectors mismatch model is established . The cost function is established based on the desired signal output power maximum principle to estimate the transmitted and received steering vectors . The bi-iteration method is proposed to solve the cost function and it is merely necessary to find out two low-dimensional convex quadratically constrained quadratic programming( QCQP) problems in per iteration . Simulation results show that the proposed method can obtain the higher output signal-to-noise-plus-interference( SINR) under the condition of severe steering vector mismatch than the conventional robust beamformers , and that the proposed method can converge fast so that it has the lower computational complexity .关键词
