为了研究网络雷达对抗系统的检测性能,对网络雷达对抗系统3种配置模型的检测覆盖范围进行了研究。建立网络雷达对抗系统模型,根据基本雷达方程推导出网络雷达对抗系统在有源模式下的覆盖范围的边界方程,并对3种配置模型的全向搜索有源覆盖范围进行仿真。由仿真结果可得,相邻的检测单元距离决定了在一定信噪比条件下系统的覆盖范围边界,间隔距离较远的检测单元的覆盖范围则是取得分集效应的基础,故网络雷达对抗系统进行配置时,应在配置区域尽量均匀分布。仿真结果证明了所提方法的可行性。

In order to study the detection performance of the network radar countermeasure system, the detection coverage of the three configuration models of the network radar countermeasure system was studied.Firstly, the network radar countermeasure system model was established.According to the basic radar equation, the boundary equation of the coverage of the network radar countermeasure system in active mode was derived, and active coverage of the three configuration models in omnidirectional search was simulated.The simulation results showed that: 1) The distance between the adjacent detection units determines the coverage boundary of the system under certain signal-to-noise ratio conditions; and 2) The coverage of the detection unit with a long separation distance is the basis for obtaining the diversity gain.Therefore, when configuring the network radar countermeasure system, it should be distributed as evenly as possible in the configuration area.The simulation results prove the feasibility of the method.
