摘　　要：针对复杂电磁环境条件下的航空战斗机突防问题,基于信干比对战斗机在突防整个航线中所受威胁进行量化分析。通过定义最大最小、全局超值最小和全局总值最小三个评估准则,针对局部威胁、全局威胁累加的不同方式进行综合分析。采用非线性回归的方式,获得目标在空中各时刻的瞬时有效反射面积,以提高评估量值的准确度。同时,对实例进行了量化数据的具体分析,通过对不同干扰方式转化时刻的寻优求取,获得全局威胁总值最小目标下的最优方案。Aiming at the penetration problem of combat aircraft in complex electromagnetic environment,the threat is ana⁃lyzed quantitatively based on signal-to-interference ratio.Three evaluation criteria are defined,which are maximum and minimum,global value minimum and global total value minimum.In order to improve the accuracy of the estimation,the instantaneous RCS of the targets obtained by using the method of Nonlinear regression.At last,the quantitative data of the example is analyzed and the op⁃timal scheme under the goal of minimum global threat value is obtained by optimizing the time of transformation of different jamming modes.
