摘　　要：针对目前靶场试验目标丢失后(特别是在发射阶段),红外经纬仪难以寻回的问题,提出了利用大视场红外凝视成像技术进行改善的方案。首先分析了靶场目标的最佳红外工作波段;其次,分析了大视场中靶场目标的成像和运动特殊性;最后,根据靶场的探测性能要求,论证了大视场红外系统的视场大小。综合多项因素,论证了视场角在57.4°~74.65°的大视场红外系统可满足靶场的探测需求,也可改善靶场试验目标丢失后难以寻回的现状,降低了漏警率。As used in shooting ranges, infrared detection device usually performs poor in recovering lost targets, in particular in taking-off stage. Thus, the wide-field staring infrared imaging technology is raised up to solve the problem. Firstly, the optimal selection of infrared detection band is analyzed about targets in shooting ranges. Then, the imaging and moving characteristics in wide-field are analyzed. Finally, the field size of infrared system is demonstrated according to the detection requirements of the field angle of 57.4°-74. 65° is suitab problem that the lost targets are difficult t shooting ranges. Tak le for detection. Mor o recover, decreasing ing various factors into account, eo th ver, it can also overcome the e missing alarm.
