Simulating Method of Target Characteristic-Angular Glint in Guidance Semi-Physical Simulation

在雷达目标特性的研究中,关于角闪烁的问题,大多数是从数学模型和数字仿真方面描述的,在制导半实物仿真系统中如何实时生成带有角闪烁特性的雷达目标回波,是对雷达目标特性研究的一个新方面。为真实实现雷达的射频目标,提出了一种在导弹制导半实物仿真系统中仿真具有角闪烁特性的雷达目标回波信号的方法,将由数学模型计算得到的角闪烁数据,引入阵列馈电控制系统中,形成带有角闪烁特性的雷达目标回波信号,采用仿真方法复现了导弹面临的电磁环境。仿真结果表明,雷达目标特性实现实际工作过程中可能的问题,为设计提供了依据。

At present,researches about angular glint are from aspects of math model and digital simulation.It＇s a new aspect of how to realize target signal with angular glint characteristic in semi-physical simulation system.This paper introduces a method for simulating radar target signals which include the angular glint in the semi-physical simulation system of missile guidance.Introducing the angular glint data calculated by math model into the control system of array feed-in.Forming a radar signal of including angular glint characteristic.Much more realistically reappear the electromagnetic environment missile be faced with.Besides,point out some questions maybe encountered during target characteristic simulation research.
