摘　　要：可见光侦察系统对目标的侦察作用距离是评价该系统性能的关键技术指标之一,在指标检验过程中有必要对其影响因素进行分析。基于可见光波段光谱反射和传输分析了目标与背景的表观对比度,提出了一种可见光侦察作用距离推算方法。利用已知实验条件下的实测数据,对其他实验条件下侦察系统的作用距离进行了推算,结果表明该方法精度较高。计算分析了单一气象因素、不同地面背景以及太阳照射角度对可见光侦察作用距离的影响,可为系统性能评估和预测提供一定的参考。The operating range of visible light reconnaissance system is one of key indexes to assess the performance of the system, and the influencing factors are analyzed when indexes of the system are tested. Firstly, the apparent contrast of target against background is analyzed based on the visible light spectral reflectance and atmospheric transmission, and an equivalent calculating method for operating range of visible light reconnaissance is proposed. Secondly, the operating range in other experi- mental conditions is calculated by using measured data from known experimental conditions, and the result shows that this meth- od has high precision. Finally, the influence of the single meteorological factor, different backgrounds and solar zenith angle on operating range are analyzed, which provide reference for evaluating and predicting the performance of the system.
