摘　　要：为了估算临近空间红外系统对助推段弹道导弹的探测距离,详细分析了弹道导弹及背景的红外辐射特性;针对基于表现对比度作用距离算法在适用性和计算精度方面的不足,引入以波数η为参量的辐射通量公式对其进行改进;通过仿真计算该系统在4.25μm^4.55μm波段对弹道导弹蒙皮、尾焰、尾喷口的探测距离,结果表明临近空间红外系统对助推段弹道导弹的探测距离可达5 000 km^38 000 km,该结论可为临近空间红外系统的设计提供数据支持。To estimate the detection range of near space infrared system for boost-phase ballistic missiles,the background infrared radiation as well as ballistic missiles is analyzed in detail. And then for the lack of applicability and accuracy of the role distance algorithm which based on the performance of contrast, the wave numberto the radiation flux formula is introduced. Finally, detection range of skin, plume and tail vents for boost-phase ballistic missile at 4.25 micron to 4.55 micron is simulated based on near space infrared system under various conditions, the results show that in the early launch time of ballistic missile, the detection range for the ballistic missile of near space infrared system can reach 5 000 km to 38 000 km, the conclusions can provide data support for the design of near space infrared system.
