摘要
为了研究微光夜视系统对目标的探测能力,从微光系统的探测方程出发,提出一种基于系统总分辨力的计算目标发现和识别概率的方法。计算表明,当其他条件不变,目标的发现和识别概率与目标表面反射率、目标临界尺寸、大气透射比有关。当目标临界尺寸变小,表面反射率与背景越接近或大气透射比减小时,其发现和识别概率就越小。最后分析并提出了相应防微光夜视探测的伪装措施。
To investigate the detection probability of low light level imaging system,a method of calculating the detection probability and recognition probability of target based on the detection equation was proposed. The result shows that when the other conditions were invariant, the discovering and recognition probability of target was related to the surface reflectivity,the size of the target and the atmospheric transmittance; and that when the target size turns smaller,the surface reflectivity gets closer to that of the background or the atmospheric transmittance becomes lower, the discovering and the recognition probability will be smaller. Finally, some relevant camouflage measurements were analyzed and provided.
