The infrared detection technology of ballistic missile based on near space platform can effectively make up the shortcomings of high-cost of traditional early warning satellites and the limited earth curvature of ground-based early warning radar. To estimate the detection range of near space-based infrared system for boost-phase ballistic missile, the background infrared radiation as well as ballistic missiles is analyzed in detail. As for the lack of applicability and accuracy of the role distance algorithm which based on the performance contrast, the wave number to the radiation flux formula is introduced. The detection ranges of skin, plume and tail nozzle for boost-phase ballistic missile at 4.25 to 4.55μm are simulated under various conditions. The results show that the improved algorithm can provide the certain engineering application value for the design of near space-based infrared system.
