A Method of Cooperation of Fuze and Warhead of Missile Based on Echo Information of UWB Array

如何保证较高的引战配合效率是超宽带引信系统研究的一个关键技术问题。为获得理想的引战配合效率,基于高斯脉冲的超宽带阵列引信,分析了弹目交汇过程中近程体目标的回波信号,指出不同方向上波形宽度与阵列方向图指向、目标方向角间存在的关系式,提出了利用回波信息估计目标中心位置的方法,在此基础上,结合弹目相对速度,确定起爆点,实现最佳引战配合。仿真结果表明:利用一维均匀超宽带阵列天线的回波进行目标距离、角度位置估计是可行的,该方法是有效的。

Because of the advantage in target detecting,target identifying and anti-jamming,the UWB radar technology has been applied to more fields.It is very important to apply the UWB radar technology to the aerial defence missile for military aim.How to gain bigger cooperative efficiency between fuze and warhead of missile is a pivotal technology problem.The problem can be solved if we can make use of the information of target echo and the relative speed of target and missile well.With the information of target echo in the encountering course of target and missile,the distance value and angle value of target can be estimated.The time domain characteristics of short range target body echo of UWB array are analyzed based on the Gaussian impulse.The mathematical relations between the pulse duration and the most radiation direction of UWB array,the angle of target position are brought forward.A way for angle estimation using pulse duration of target echo is proposed.And the method of improving the cooperation efficiency of fuze and warhead of missile is educed based on the echo information of UWB array and the relative speed between target and missile.So the best explosion location of warhead of missile for killing target can be calculated.Through simulation and calculation,the feasibility of the new method is verified.
