摘要
训练用靶机尺寸远小于实战中的飞机,其RCS数值大小和起伏特性与飞机存在较大的差别。为了以低廉的价格为部队训练提供高逼真度的模拟靶机,在靶机机头、翼下等位置放置一定样式的可变RCS龙勃透镜,可以得到类似实战中飞机的RCS特性。通过控制龙勃透镜的反射面位置可以改变其RCS数值,实现模拟靶机RCS的数值变化。采用靶机挂载可变RCS龙勃透镜对MQ-1无人机前向RCS起伏特性进行了模拟,取得了较好的效果,可为采用靶机挂载可变RCS龙勃透镜模拟作战飞机的全向RCS特性提供借鉴。
The size of the military training drone aircraft is much smaller than that of the aircraft in actual combat,at the same time the RCS value and fluctuation characteristics of the drone aircraft are quite different from that of the aircraft.In order to provide high fidelity simulated target aircraft for training at a low price,Luneberg lens are arranged at specific positions such as the nose and under the wing of the drone aircraft,and the fluctuation characteristics of the radar cross section(RCS)is similar to the real aircraft.Based on the mechanism that controlling the movement of the reflecting surface of the Luneberg lens can realize the change of the RCS,the forward RCS fluctuation characteristics of MQ-1 UAV is simulated by using the drone mounted with variable RCS Luneberg lens,and good results are obtained,which can provide a reference for using the drone to simulate the omni-directional RCS characteristics of the combat aircraft.
