Robust Transmitting Beamforming for MIMO Radar

摘要

摘要: 针对发射导向矢量存在未知误差的问题，该文提出了一种MIMO雷达稳健的发射波束形成算法(Robust Transmitting Beamforming, RTB)。该算法在稳健的接收波束形成算法的基础上，以最大化最差情况输出信干噪比为优化准则，对发射导向矢量误差做稳健的发射波束形成。RTB算法属于对角加载方法。仿真结果表明，相比于已有算法，RTB算法的稳健性更好、计算复杂度更低、收敛速度更快。

Abstract: A Robust Transmitting Beamforming (RTB) algorithm is proposed for MIMO radar in the presence of unknown transmitted array distortions. The proposed beamformer, which is cascaded with the robust receiving beamformer, is based on the maximization of worst-case Signal-to-Interference-plus-Noise Ratio (SINR). The proposed beamformer belongs to the class of diagonal loading techniques. Numerical experiments show that the proposed beamformer has better robustness, lower computational complexity and faster convergence rate as compared with the other robust beamforming algorithms.
