设计了隐身飞机采取S 机动通过分层部署式、环形雷达网的作战场景,得到了飞机相对每部雷达的动态雷达散射截面积;然后,采用swerlingI 型雷达检测模型,计算了单部雷达的检测概率;最后,采用秩K 判断准则,得到不同秩下,组网雷达的联合探测概率和虚警概率。当秩K =2 时的六雷达组网系统,具有较高的检测概率,较低的雷达虚警概率。该文对于雷达组网对隐身飞机的探测、隐身飞机突防具有一定的指导意义。

Netted radar is an effective method to detect stealth aircraft. In this paper. The operation background that stealth aircraft through ' S ' maneuver come across netted-radar battleground is designed, and the aircraft's dynamic RCS is obtained. SwerlingI model of radar detection is adopted and each radar's detection probability is obtained. Data fusion rule by K order is adopted to calculate detection probability and false alarm probability of netted radar system in different K. We found in the netted radar system with 6 radars, when K is equal to 2, the netted radar system have the best performance. This paper provides theory for netted radar detecting stealth aircraft.
