无人机光电探测距离分析

针对低空消费级无人机这种低慢小目标,采用理论建模和对实验中飞行温度参数实测的方法,建立了目标红外辐射模型以及背景辐射参数模型,得到了与实测结果比较相符的红外探测距离。指出了对这类低红外辐射目标,对阳光反射和背景噪声必须精细估算才能得到比较准确的红外作用距离。另外,通过对分析结果的讨论,对未来无人机红外探测系统的设计提出了一些建议。

Analysis on infrared detection range for unmanned aerial vehicle

Aiming at the small consumer UAV with low-altitude,infrared radiation model of the target and radiation parameter model of the background were established by theoretical modeling and experimental measurement of flight temperature parameters,then the infrared detection range was obtained,and it is consistent with the measured results.For the target with weak infrared radiation,the more accurate infrared operating range can be gotten only carefully estimating the sunlight reflection and background noise.Through the analysis of the results,some advice is given for the design of future UAV infrared detection system.
