一种半主动激光红外雷达三模复合光学系统设计

A Design of Optical System Composed by Semi-active Laser, Infrared and Radar

介绍了一种紧凑型的半主动激光、红外、雷达三模复合光学系统,半主动激光、红外光学系统采用折反式光路结构,雷达系统采用抛物面天线发射接收信号。3种导引模式共用一个主反射镜,半主动激光系统与红外系统在主反射镜处光线分离,雷达波与红外光在主反射镜共口径反射后,在次反射镜处信号分离,在紧凑空间内实现了3种导引模式的融合。

A compact optical system composed of semi-active laser, infrared and radar is introduced. The catadioptric structure is used in semi-active laser and infrared system. The signal is launched and received by a parabolic antenna in radar system. The same reflective mirror is used in the three guide models, the signal of semi-active laser and infrared system is split at the reflective mirror, the radar signal and infrared system is split at the second reflective mirror after reflected by the primary mirror. So the three guide models are realized in a compact space.
