摘　　要：对自适应旁瓣对消如何用于相控阵单脉冲测角进行了研究。使用常规自适应旁瓣对消方法,辅助天线中的期望信号会导致测角误差;若采用阵列输入经期望信号阻塞矩阵处理后产生辅助波束的改进方法,则可消除这一误差。仿真结果表明了改进方法的有效性。The application of adaptive sidelobe cancellation to a phased array using monopoulse angle measurement is studied. The desired signal in the auxiliary antennas may cause angle measurement error by using conventional adaptive sidelobe cancellation method. If the improved method is adopted, in which array input is processed by signal blocking matrix and then auxiliary beams are generated, the angle measurement error due to the desired signal in the auxiliary antennas can be eliminated. Computer simulation results show that the improved method is effective.
