【摘要】：角闪烁是现代防空制导武器的主要误差源。针对隐身飞机目标动态角闪烁外场测量难度大、耗时长、精度低的问题,提出了一种基于FEKO软件的雷达目标动态角闪烁特性的实时仿真方法。首先,对雷达坐标系和目标坐标系进行了坐标转换,获得了目标模型飞行随时间变化的方位角和俯仰角;然后,介绍了利用FEKO仿真计算目标动态角闪烁的方法及其步骤;最后,以隐身飞机目标为例,通过该方法仿真获得蛇形机动下的目标实时动态角闪烁特性。仿真结果表明:该方法能获得目标实时电场散射信息,进而计算出目标的角闪烁信息。该研究为防空制导武器抗诱偏、降低脱靶量等方面提供了理论分析和实验依据。
[Abstract]:Angle flicker is the main error source of modern air defense guidance weapon. In order to solve the problems of high difficulty, long time consuming and low precision, a real-time simulation method of radar target dynamic angle scintillation based on FEKO software is proposed. Firstly, the coordinate transformation of radar coordinate system and target coordinate system is carried out, and the azimuth and pitch angle of target model flying with time are obtained. Then, the method and steps of calculating the dynamic angle flicker of target by FEKO simulation are introduced. Taking stealth aircraft as an example, the real-time dynamic angular flicker characteristics of a snake maneuvering target are obtained by simulation. The simulation results show that this method can obtain the real-time electric field scattering information of the target and then calculate the angular flicker information of the target. The research provides theoretical analysis and experimental basis for anti-decoy and reducing miss distance of air defense guided weapon.
