摘　　要：为了分析存在幅相误差的自适应旁瓣对消系统(ASLC)性能,推导了主辅通道存在幅度不一致性、相位不一致性以及同时存在幅相误差时ASLC系统任意通道间的相关系数公式,以干扰对消比为依据,给出了上述条件下的计算机仿真结果,得出了相应的结论。理论分析和仿真结果表明幅相误差对自适应旁瓣对消系统具有重要的影响,必须加以克服。For performance analysis of ASLC with amplitude and phase error, the correlation coefficient formula between the main and auxiliary channels are presented for conditions with amplitude error, phase error, and with both. The simulation results are presented under these conditions. Based on the cancellation ratio, the theoretic analysis and simulation results are presented. This shows that the amplitude and phase error has important effect on ASLC.
