In the presence of unknown transmitting array distortions, a robust adaptive mismatched filter (RAMiF) is proposed, which is cascaded with the robust receiving adaptive beamformer. 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.

Key words: transmitting array distortions, robust receiving adaptive beamformer, mismatched filter
