基于副通道强制赋零的空间主要目标捕获技术研究

Space main target acquisition technology based on sub-channel forced zeroing

空间目标飞行过程中常出现单目标分离为多目标现象,造成单脉冲雷达受强伴飞目标干扰,难以捕获空间主要目标,易于丢失感兴趣的主要目标。提出采用副通道精准区间强制赋零方法,解决空间主要目标的可靠捕获的难题。采用雷达主副通道间目标固定映射关系,获取伴飞目标在副通道的精准位置,并对该位置区间进行强制赋零操作,有效抑制了伴飞目标对雷达副通道的干扰,提升了单脉冲雷达的捕获跟踪空间主要目标的能力和效率。

The separation phenomenon from single target to multiple targets often occurs during the flight of space targets,which causes the strong companion flight target interference with the mono-pulse radar.So it is difficult to capture the space main target,but easy to lose the main target of interest.The application of forced zeroing method is proposed in sub-channel accurate interval,to solve the reliable capture problem of the space main targets.The target fixed mapping relation between the sub-channels is applied to capture the precise position of the companion flight target in sub-channel,and the forced zeroing is operated in its position interval,and then the interference of the companion flight target to radar sub-channel is effectively suppressed.In the end,the capability and efficiency of the space main targets acquisition and tracking is enhanced for mono-pulse radar.
