| 高重频脉冲干扰可压制宽带接收机，从而实现对反辐射武器的防护以保护雷达的安全。为明确其对被动导引头的有效压制区，从高重频脉冲的信号特征出发，首先分析了干扰脉冲对被动导引头的作用机理并进行了仿真验证；其次考虑与雷达的电磁兼容问题进而明确干扰机的部署位置，并依据功率准则给出了有效压制区的计算方法；最后以单站干扰为例对影响压制区大小的因素进行分析，并对多站协同干扰时的压制区进行了仿真。结果表明，有效压制区的大小与干扰脉冲的功率、重频、脉宽有关，调整干扰参数的同时必须保证干扰机部署于临界线之外，多部干扰机协同干扰能有效扩大压制区。 |

| Abstract: |
| High pulse repetition frequency(PRF) pulses can suppress wide band receivers to achieve interference with anti radiation weapons to protect the radar.In order to clarify the effective suppression zone of passive seeker，starting from the signal characteristics of the high PRF pulses，the mechanism of the interference pulses on the passive seeker is firstly analyzed and verified by simulation. Secondly，considering the electromagnetic compatibility of the radar and further clarifying the location of the jammers，and the calculation method of the effective suppression zone is given according to the power criterion. Finally，the single site interference is used as an example to analyze the factors affecting the size of the suppression zone，and the simulation of the suppression zone during multi station interference is performed. The results show that the size of the effective suppression zone is related to the power，repetition frequency，and pulse width of the interference pulse. When adjusting the interference parameters，it must be ensured that the jammer is deployed outside the critical line，and multi jammer interference can effectively expand the suppression zone. |
