红外昼夜跟瞄系统工作波段选择与分析
|
摘要
针对红外系统设计中工作波段选择问题,从探测器性能、光学弥散斑、大气传输特性、目标与背景辐射特性、海杂波干扰等多个方面对中波和长波红外进行了对比分析;制定了详细的中波和长波红外热像仪昼夜探测效果摸底试验方案,得出在不同时间、不同气象条件下2种探测器对相同目标的探测试验数据。结合试验数据与理论分析,提出红外系统在用于对岸远程昼夜探测情况下波段选择的建议。
Aiming at the selection of the working band in the infrared system design,the mid-wave and longwave infrared were compared and analyzed from several aspects such as detector performance,optical diffusion spot,atmospheric transmission characteristics,target and background radiation characteristics,and sea clutter interference.The detailed test schemes to get the day-night detection effect of mid-wave and long-wave infrared thermal imager were formulated,and a great deal of data of the two detectors at different times and different weathers was obtained.Combined with experimental data and theoretical analysis,the proposal of band selection for infrared system using in remote day and night detection on the other shore was put forward.
