传统的红外探测距离模型主要用于地面目标的检测，载机飞行高度也比较低。在凝视型红外热探测器的基础上，对临近空间的大气环境进行了详细分析，建立了背景辐射模型。在此基础上提出了临近空间飞行器的红外探测距离模型，对红外波段适用范围进行了讨论。计算结果表明，在临近空间环境下，红外波段都有较好的探测结果，在短波下探测时，背景辐射对其探测结果影响很大。
傳統的紅外探測距離模型主要用于地麵目標的檢測，載機飛行高度也比較低。在凝視型紅外熱探測器的基礎上，對臨近空間的大氣環境進行瞭詳細分析，建立瞭揹景輻射模型。在此基礎上提齣瞭臨近空間飛行器的紅外探測距離模型，對紅外波段適用範圍進行瞭討論。計算結果錶明，在臨近空間環境下，紅外波段都有較好的探測結果，在短波下探測時，揹景輻射對其探測結果影響很大。

Traditional infrared detection distance model is mainly used for ground target detection,and the flying height of the carrier aircraft is relatively low .Based on analysis to staring infrared thermal detectors,the near space environment was studied and a background radiation model was established .Based on which,an infrared detection distance model of near space aerocraft was proposed,and the application range of infrared bands was discussed .The results show that:1) in the near space environment,infrared band has better detection results;and 2 ) in the detection using shortwave,the background radiation has a great effect on the detection results .
