摘　　要：介绍了一种红外系统对海面低空飞行导弹最大探测距离的计算方法,建立了以涡喷发动机为动力的导弹全向中波红外辐射和海面水平传输计算模型,针对导弹中波红外辐射及其在大气中的传输衰减和红外探测器对导弹红外辐射的响应在不同波长时皆为非均匀的特性,提出了将导弹在3～5μm波段的红外辐射分成若干小区间计算,与对应小区间大气的海面水平传输衰减和红外探测器光谱响应曲线相对值综合后,计算红外探测系统对导弹最大探测距离的方法。最后,将理论计算结果与试验测试数据进行了对比,结果显示理论计算结果与试验测试结果有较好的一致性。An introduction is given to the improved method for calculating the maximum detection distance of infrared system in searching low-altitude flying missile upon sea level. The calculation models of aU-round medium-wave infrared radiation of turbojet engine-powered missiles and the sea level transmission were established. Considering that both the atmospheric attenuation of the missiles＇ medium-wave infrared radiation in transmission and the responses of infrared detection system were inhomogeneous for different wavelengths, the process can be divided into three steps. Firstly, the missiles＇ infrared radiation in the 3 - 5 μm band was subdivided into fine intervals to be calculated. Then the coefficients of corresponding fine intervals of sea-level atmospheric attenuation and the relative value of infrared detector＇s spectral response curve were integrated to calculate the ultimate detection range of infrared detection system. Finally, the theoretical results and experimental testing data were compared with each other. The results of theoretical calculations and the results of experimental are in good agreement.
