摘要
激光辐照到卫星的星载相机光电探测器上会形成干扰光斑,该干扰光斑会使星载相机“致盲”,从而无法侦察到地面部分区域。本文以可见光波段激光辐照星载相机为例,建立了激光干扰星载相机的地面防护能力评估模型,分析了影响防护区域大小的主要因素,定量评估了激光对星载相机的地面防护效能。
Laser irradiation on photo detectors of satellite-borne camera will form interference spots.The spots will cause blindness of the space borne camera,which will make it impossible to detect parts of the ground.Taking visible-band laser-irradiated satellite-borne camera as an example,the evaluation model of ground protection capability of laser-jammed space-borne camera is established,the main factors affecting the size of protection area are analyzed,and the ground protection effectiveness of laser-irradiated satellite-borne camera is evaluated quantitatively.
