主动雷达成像导引头几个问题的研究

Research on Active Radar Imaging Seeker

研究了主动雷达成像导引头的工作模式、成像方法和系统控制方式。通过对雷达导引头子孔径数据进行聚束处理 ,在短时间和大前斜视角情况下完成对其天线波束覆盖的地面目标区域的快速成像 ,利用雷达图像跟踪和单脉冲跟踪两种跟踪模式分别解决对目标的远距离前斜视跟踪和近距离前视跟踪问题。

The operation mode, imaging method and system′s control problem of a active radar imaging seeker are investigated. By means of radar′s subaperture data spotlight processing, the quick look image formation is completed in a short time and a large squint angle with a ground scenery corresponding to the antenna beam width. The radar image track mode is used for the tracking of long range target with a large squint angle and mono pulse track mode is used for the tracking of short range target in seeker's flight direction, respectively. The specifications of a short range active radar imaging seeker in Ku and Ka band are analyzed and its main technical parameters are introduced.
