无人侦察机红外辐射特性测试与视距估算

Infrared radiation characteristic measuring and visual range prediction of reconnaissance unmanned aerial vehicle

采用长波测温热像仪及光谱辐射计,测试研究了某型短程固定翼无人侦察机的红外辐射特性,给出了其静、动态光谱辐射特性及热场分布特征结果。根据约翰逊准则的判据,并采用坐标变换方法,将目标/背景温差曲线与MRTD曲线在同一坐标系中进行变换与数据拟合,求得某一典型气象条件下无人侦察机的被探测/识别距离。简要介绍了无人侦察机红外隐身的可能途径。试验数据为其隐身性能的改进设计提供了重要依据。

Infrared radiation characteristic of a kind of short-range reconnaissance unmanned aerial vehicle(UAV) with fixed wing is measured using a long-wave thermovision system and spectroradiometer, its spectrometric characteristic and thermal field distribution characteristic on the static state and flying state is presented respectively. Based on Johnson criterion, the target/background temperature difference curve and MRTD curve is transformed and framed in a same system of coordinate with a coordinate transfor...
