基于脉冲多普勒体制的火控雷达重频选择方法
|
摘要
当前的火控雷达多采取脉冲多普勒体制,其在目标截获阶段需要快速检测到引导数据所指示的目标,而受距离盲区、速度盲区及引导数据精度等因素的约束,雷达所使用的工作重频的可检测区域是否能覆盖目标,将直接影响到对目标的快速捕获和跟踪,进而决定雷达所从属的武器系统对目标的火力反击速度。文中提出一种在这些约束条件下重频集合的选取方法,并结合仿真进行了说明。
The current fire control radar adopts the pulse Doppler system,which needs to quickly detect the target indicated by the guidance data in the target interception stage,and is constrained by factors such as distance dead zone,speed blind zone and guidance data accuracy.Whether the reproducible detectable area can cover the target will directly affect the fast capture and tracking of the target, and then determine the speed of the firepower counterattack of the weapon system to which the radar belongs.In this paper,the selection method of the repetitive frequency set under certain constraints is given,and the simulation is described.
