                    首先定义了一个反映目标可探测程度的物理量——可测度,目标的可测度值越大,表明它越容易被探测到。然后通过目标及大气辐射和传输计算,分析了温度、压强、相对湿度、能见度等参数的变化,对空中目标的红外可测度的影响。计算结果表明:大气的温度和能见度对目标可测度有很大的影响。大气温度愈高,目标可测度值愈大;能见度越好,目标越容易被探测到。大气湿度和压强对目标可测度的影响较小:目标可测度值随大气湿度和压强的增大而略有减小。
                
                A new physics quantifier detectability, which is used to describe how difficult it is to detect a target, has been defined. Through a mount of simulating calculation, the influence of the atmospheric temperature, pressure, humidity and visibility to aerial infrared targets has been analyzed. The conclusion indicates that: the atmospheric temperature and visibility would influence the targets' detectability strongly; the atmospheric humidity and pressure would influence the targets' detectabilitv slightlv
