摘　　要：依据小哈德逊经典探测距离估算公式,从工程应用角度出发提出了一种改进红外探测距离估算方法。该方法在原理论基础上依据目标辐射特性、光学系统设计能力、探测器性能、大气传输等方面进行估算,同时分析了光学系统能量利用效率、红外探测器电路噪声、目标背景辐射影响对红外探测性能的影响。最后通过仿真分析,将经典方法距离估算结果与经过改进方法修正后的结果进行比较,验证了改进后距离估算方法在IRST系统设计评估中的有效性。A novel method of Infrared Search and Track System（IRST）which is modified from the Hudson＇s classic distance formulais proposed from the engineering application perspective.The modified formula not only calculates distance by the target radiation characteristicthe optical system designthe detector performance and the atmospheric transmittancebut also analyzes the influence brought by the target＇s energy utilization efficiencythe detector circuit noise and the background radiation.Finallythe superiority of the novel formula is verified in the empty distance measurement fieldwhich is deduced from the comparison between the results of the novel method and that of the Hudson＇s classic distance formula.
