Abstract：This paper proposes an improved narrow-band model based on a correction function for calculating infrared radiation from two types of nuclear cruise missile plumes. The model replaces narrow-band parameters in the Curtis-Godson (CG) approximation with path-equivalent narrow-band parameters to address accuracy degradation in non-uniform combustion systems. Compared with experimental data from Reference[1], the improved narrow-band model with correction function demonstrates better alignment with experimental results than traditional CG-based narrow-band models, showing accuracy improvements of 13.29%, 18.01%, and 8.4% in the 2.7, 4.3, and 3～5 μm bands, respectively. Building on this foundation, flow field parameters varying along trajectory points for AGM-86B-type and AGM-158B-type missiles are calculated. By solving the radiative transfer equation using the Line of Sight (LOS) method, an infrared radiation calculation model for nuclear cruise missile plumes is established, enabling computation and analysis of infrared radiation characteristics at flight altitudes ranging from 1 to 20 km. Results indicate that for AGM-86B-type missiles, radiation intensities in the 2.7 and 4.3 μm bands exhibit similar altitude-dependent trends, reaching peak signals at 5 km altitude during the latter half of the flight trajectory. For AGM-158B-type cruise missiles during their flight trajectory from 20 to 1 km, the radiation intensity in the 4.3 μm band is consistently higher than that in the 2.7 μm band. These findings provide theoretical support for early-stage missile type identification and interception of these two missile categories.
