Abstract
To solve the beam to beam interfereace problem,a synthesis method of beam pattern of multi-target TT&C antenna based on the null points constraints is presented. The method gains the closed solu-tion of the optimal weight vector with the zero constraint on the direction of interference,and generates the beam pattern with the interference rejection capability. The simulation results show the proposed method of beam pattern may form effective null points in multiple directions under the condition of maintaining the o-riginal beam pattern feature. The method is tested on the equivalent two-meter caliber TT&C antenna for multi-target in hemispherical coverage and the result shows that the rejection ability in interference direc-tion is greater than 60 dB,which proves the correctness of the solution.关键词
