基于锥形透镜光纤阵列的激光告警接收机研究

Multi-window Laser Warning Reciever Based on Tapered and Lesed Fiber Arrary

为了提高多窗口激光告警接收机方位探测精度以及抗电磁干扰性能,提出了基于锥形透镜光纤阵列的多窗口激光告警接收机设计.研究了锥形透镜光纤视场原理,使用经纬度分割原理研究了均匀分割视场空间方法,开发的原理样机利用6个三角形探测窗口和6个梯形探测窗口将上半球视场空间均匀分割成36个子视场,每个子视场方位角和俯仰角范围均为0°～30°,并经过实验验证,达到了设计目的.

In order to improve the orientation detection precision and anti electromagnetic interference performance of muhi-window laser warning reciever（ MWLWR）. A new MWLWR has been proposed, based on tepered lensed fiber arrary. The field of view of the tepered lensed fiber has been analysised in theoretically. The MWLWR prototype has beed divided into 12 equal small field of view by meridian and latitude line on the sphere, six triangle windows and six trapezoid windows, and the experimental results showed that the hemispherical field of view has been segmented into 36 uniform areas with azimuth angle range 30° and elevahion angle range 30°.
