摘要
文章通过对全景系统研究现状以及未来使用要求的分析,给出了全景系统的一种新的设计思想。该系统利用光学方法将四路光合成为一路光,使用一个探测器替代多个探测器,降低了系统的造价,减小了体积。在3μm～4.3μm和4.3μm～5μm两个波段进行了相参设计,使得系统具有优于单色探测系统的探测能力和复杂环境下的目标识别与判别能力,提高了有效侦察率,大大降低了虚警率。系统采用了360°×90°(水平×垂直)视场的45°×11.25°缩比视场,像质优良。
Through analysis of the current status and future requirement of a panorama system, a new design idea of the panorama system is given. In the system, an optical method is used to combine four optical paths into one optical path and a detector is used to replace several detectors so that its cost and volume are reduced. Since the coherent design is used in both the spectral band of 3μm to 4.3μm and the spectral band of 4.3μm to 5μm, the target dectection and recognition capability of the system is better than that of the monochromatic system under the complicated environment. Its effective reconnaissance probability is improved and its false alarm probability is reduced greatly. Because the 45° by 90° field of view compressed proportionally from the 360° by 90° field of view is used, its imaging quality is fine.
