摘要
针对机载自卫电子对抗系统地面测试时模拟器与飞机位置相对固定、检测结果不精确的问题,提出一种基于残差修正的轨迹模拟方法,首先对飞机三维位置坐标构建MGM(1,3)模型,通过对获得的模拟值进行多次残差修正以进行改进,最后得到轨迹模拟表达式。实验仿真表明:与传统的MGM(1,3)模型相比,基于残差修正的MGM(1,3)模型相对误差较小,避免了因数据跳动较大而引起的预测风险,提高了模拟结果的可靠性,基本符合机载电子对抗系统地面测试的需要。
In view of the problem that the simulator and the aircraft are fixed in position and the detection result is inaccurate in the ground test of airborne self-defense electronic countermeasures system,this paper proposes a trajectory simulation method based on residual correction.Firstly,the MGM is constructed on the three-dimensional position coordinates of the aircraft(1,3)The model is improved by performing multiple residual corrections on the obtained analog values,and finally obtains a trajectory simulation expression.The experimental simulation shows that compared with the traditional MGM(1,3)model,the relative error of the MGM(1,3)model based on residual correction is small,avoiding the prediction risk caused by the large data jitter and improving the simulation result.The reliability is basically in line with the needs of ground testing of airborne electronic countermeasures systems.
