| 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。

| Abstract: | 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. |
