摘要

针对高轨道红外探测系统，分析了弹道导弹尾焰的红外探测性能。采用大气校正软件PCModWin对不同高度和不同太阳天顶角下的大气透过率和大气背景辐射进行了计算。根据计算结果，对系统作用距离、信噪比和信杂比等红外探测性能参数进行了分析。分析表明：信杂比指标满足系统设定要求；作用距离和信噪比性能指标并不理想；通过改善探测器和光学系统参数提高性能指标，可达到系统设定要求。

Abstract

Aiming at geosynchronous orbit infrared detection system,the infrared detection performance of the ballistic missile plume is analyzed. The atmospheric transmittance and the background radiance at different heights and different sun zenith angles were computed with the atmospheric radiance model software of PCModWin. According to the obtained results,the performance indexes of infrared system for the plume detection of the ballistic missile,including the effective range,SNR (signal-to-noise ratio) and SCR (signal-to-clutter ratio),were analyzed. The results indicate that SCR performance index can meet the needs of the infrared detection system,but the performance of SNR and the effective range are not satisfactory. The performance of the infrared detection system can be improving the parameters of the sensors and the optical system.
