摘要
为对5GAT靶机的RCS特性进行分析,采用外形逆向建模和RCS仿真计算的方法,对UHF~X波段该靶机单站和双站RCS进行了仿真计算。仿真结果表明:通过采用综合外形隐身设计手段,该靶机在高频的C和X波段处于较低的散射水平,头向和侧向和RCS均值随频率升高呈迅速递减的趋势。通过几何特性相似的设计手段,该型靶机能在一定程度上模拟五代机的RCS特性。
Conversely shape modeling and RCS simulation are used to analyze the bistatic RCS behavior and monostatic RCS behavior of 5 GAT from UHF through X band.The RCS simulation result demonstrates that the scattering level is low under C band and X band by shaping.The mean values in frontal scope and lateral scope shapely reduce with the frequency ascending.This target drone is capable to simulate the RCS behavior of 5fighter by employing geometric similarity.
