摘要 针对发射导向矢量存在未知误差的问题,提出了一种MIMO雷达稳健的自适应失配滤波器(Robust Adaptive Mismatched Filter,RAMiF)设计算法.该算法在稳健的接收波束形成算法的基础上,对其输出做稳健的失配滤波处理,以一定的主瓣电平损失为代价换取更低的旁瓣电平,从而提高系统对发射导向矢量误差的稳健性.仿真结果表明该滤波器在信噪比较高的情况下对发射导向矢量误差具有自适应的稳健性. In the presence of unknown transmitting array distortions, a robust adaptive mismatched filter （RAMiF） is proposed, which is cascaded with the robust receiving adaptive beamforrner. At the cost of losing some mainlobe level, the sidelobe level of the proposed filter is suppressed effectively, which provides sufficient robustness against the mismatches between the presumed and the actual transmitting steering vectors. Simulation results demonstrate that the proposed filter has adaptive robustness against the transmitting steering vector errors when the signal-to-noise ratio is relatively high.
