摘　　要：针对雷达在对抗截获接收机时,临界被截获距离难以直接测试的问题,论文首先分别推导了雷达采用常规波形和LPI波形探测时的临界被截获距离表达式。然后,对不同场景下的临界被截获距离进行了等效建模分析。最后,通过仿真试验验证了临界被截获距离等效模型的准确性,仿真结果表明,对于目标RCS为10m2,截获系统灵敏度为-70dBm,雷达采用LPI波形探测时,临界被截获距离在120km以上。To solve the problem that it is difficult to directly test the critical intercepted distance between radar and intercept receiver,the expressions of the critical intercepted distance of conventional waveform and LPI waveform are derived respectively.Then,the equivalent model of the critical intercepted distance in different scenarios is analyzed.Finally,the accuracy of the equiva⁃lent model of the critical intercepted distance is verified by simulation experiments,and the simulation results show that the critical intercepted distance is more than 120km when LPI waveform detection is used.When RCS is 10m^(2),intercept sensitivity is-70dBm.
