摘　　要：飞机执行军事任务时,其过程一般表现为动态目标在复杂环境下的高速运动。飞机动态实测与静态测量得到的电磁散射特性存在较大差异,导致其角闪烁的计算方式也存在不同,飞机动态飞行时过程较为复杂,致使角闪烁计算过程也更加繁琐。本文从动目标角闪烁的角度出发,首先通过两个静态目标角闪烁算例验证了角闪烁计算部分的正确性,再利用飞机实测的惯导数据,通过姿态解算和电磁散射特性计算,实现飞机真实运动情况下的角闪烁计算。经模拟试验表明,该方法有效,此工作对于研究复杂动目标角闪烁具有一定的工程应用价值。When an aircraft performs a military mission,it is considered to be as a high-speed movement of a dynamic target in a complex environment.There is a larger difference between the electromagnetic scattering characteristics obtained by the dynamic measurement of the aircraft and the static measurement,which results in different calculation methods of the angular glint.The process of the aircraft dynamic flight is more complicated,which makes the angular glint calculation process more complicated.From the perspective of the angular glint of the moving target,this paper first verifies the correctness of the angular glint calculation part through two static target angular glint calculation examples,and then realizes the angular glint studies of moving target based on the more mature attitude calculation and electromagnetic scattering characteristic calculation.The modeling software can import any model and use the secondary development function to achieve attitude calculation and calculate electromagnetic scattering characteristics to complete the angular glint calculation of the moving target,which avoids the cross use of multiple software and greatly improves the convenience of the angular glint research process.This work has certain theoretical research significance and engineering application value for the study of complex moving target angular glint.
