针对激光引信使用中弹目交汇条件不确定带来的目标探测接收镜头回波弥散斑尺寸变化较大的问题,提出了基于远心镜头的激光探测目标回波弥散斑控制方法。该方法采用远心镜头构型设计激光引信光学接收系统,通过合理匹配远心镜头的光圈 F 数和焦距 f 等参数设置,使远心镜头达到较大的景深,同时采用两个远心镜头拼装共用一个光电探测器,既不增加激光引信的外形尺寸,又弥补了单个扇区90°接收视场的不足,从而实现了不同弹目交汇条件下激光探测目标回波弥散斑的尺寸控制。仿真结果表明,在不同距离不同角度接收的目标回波弥散斑尺寸均小于光电探测器光敏面尺寸半径50μm,这样保证了光电探测器可以接收到全部的回波能量,表明远心镜头实现了对目标回波产生的弥散斑尺寸变化的控制。

For the target detection echo receiving lens diffuse spot size changed greatly caused by uncertainty of the target missile intersection in the use of laser fuze,the target echo spot control of laser detection by telecen-tric lens was proposed in this paper.The method used telecentric lens configuration design of laser fuze optical receiving system,by reasonable matching telecentric lens aperture F number and focal length f and etc.parame-ters setting,to make the telecentric lens possessing a larger depth of field,and using two telecentric lens assem-bly sharing a photoelectric detector,not increased the size of the laser fuze,and made up for the lack of a single sector receiving field of view 90 degrees,to achieve different target intersection target echo spot laser detection under the condition of size control.The simulations revealed that the target echo spot in different length and dif-ferent degrees was smaller than 50 μm of photoelectric detector,which could make sure that the photoelectric detector collecting all energy of target echo.
