Abstract：In the array signal processing, the inverse beamforming for interference suppression algorithm uses the azimuth information of interference to estimate and suppress the interference. In the complex marine environment the phase of the interference which is received by the array has the random disturbances, there is a big deviation between the actual interference and the interference which is estimated by the algorithm, which makes the effect of the interference suppression not good. In order to adapt the random disturbances of the phase of the interference, the inverse beamforming for interference suppression algorithm with good robust takes the random disturbances into full consideration and uses the interference reconstruction matrix to estimate the interference. In this case the estimated interference is closer to the actual interference signal and the result of interference suppression is better. The proposed method takes the random disturbances of the phase of the interference into full consideration, so it shows good robust in the complex ocean environment. Both the theoretical analysis and the computer simulation results show the effectiveness of the proposed method.
