摘　　要：船用导航雷达工作时同时开机数量多、距离近、频率等参数相同或相近,故同频干扰已成为急需解决的问题。本文介绍了同频干扰的产生机理和特性,分析了抗同频干扰的常规方法及其局限性,重点阐述了一种抗同频干扰时域信号处理技术。仿真和试验结果验证了该方法的有效性。Multiple adjacent marine navigation radars with the same or similar frequency are operating simultaneously. Therefore,the shared frequency interference has become an issue that needs to be solved urgently. The generation mechanism and characteristics of the shared frequency interference are introduced,and the conventional methods of resisting the shared frequency interference and their limitations are analyzed with an emphasis on the time-domain signal processing technology. The simulation and test results indicate that the method is effective.
