摘　　要：在200-400nm紫外波段，阳光辐射被大气中的臭氧层强烈吸收，存在所谓的“太阳光谱盲区”；而背景环境中景物的温度不足以产生有影响的紫外辐射。因此，在低空环境中，紫外探测器很容易探测到微弱的紫外辐射，具有很低的虚警率。开展了基于紫外ICCD的导弹逼近告警系统研究、紫外目标特性及大气传输研究、大视场窄带紫外光学系统研究及紫外图像处理等研究，进行了各种测试试验，取得了预期的研究成果。In the region of 200-400nm,the emission of the sun is almost completely absorbed by high altitude atmospheric ozone, called the＂solar blind＂. Additionally,objects in the background are too cool to emit a significant amount of UV radiation. Thus at lower attitude environment even dim UV source are easily to be detected with lower false alarm rate. The missile approach warning system based on ultraviolet ICCD, the signature of ultraviolet object,transmission characteristics of ultraviolet emission, wide field of view lens with narrow band in UV region and UV image process about the warning system are studied. Various tests are done to prove that the alarm system operates well.
