N2 - In this paper, a new technology of mainlobe interference suppression for radar system is proposed based on large aperture auxiliary array. The geometry of auxiliary array is firstly designed, and then two adaptive beamforming methods are presented respectively. In method one, the interference received by the auxiliary array is utilized to cancel the mainlobe interference of main radar based on the rule of Minimum Mean Square Error (MMSE). In method two, the auxiliary array and the main radar are combined to construct one whole phased antenna array to suppress the mainlobe interference of main radar based on the rule of Maximum Signal to Interference plus Noise Ratio (MSINR), which can not only suppress the mainlobe interference effectively but also improve significantly the gain of target. The simulations are carried out to illustrate the performance of proposed methods.
