With the requirement of the research on the stealthy aircraft’s infrared characteristic, the design and analysis have got more attention. Depend on synthesizing the main factors, include the surface IR radiation, the scatter radiation from the environment, the temperature distribution and the coat distribution of the surface, which effect the stealthy capability, a stealthy aircraft’s IR characteristic simulation model was proposed. Based on MODTRAN, the environment radiation model was built and was used in the simulation model. Finally, the proposed simulation mode was used in design and optimizing one stealthy aircraft, using combined the muti-island genetic algorithm with the sequential quadratic programming. The results of the mid-wave and long-wave radiation were got separately. These results provided considerable reference for infrared stealthy aircraft’s design.

“…The infrared signature research of the target is the premise of analyzing its detectability (Li, N. et al 2016;Chen, H. et al 2019;Cheng, W. et al 2019;Sun, W. et al 2019;Wu, S. et al 2019;Nam, J. et al 2020). The high-temperature plume and the high-temperature of the aircraft skin produced by the stealth aircraft in highspeed flight have prominent infrared radiation characteristics.…”

Advances in infrared detection techniques require novel spectrum dynamicmodification strategies capable of sensing unprecedentedly low target radiant intensities. A conventional fixed-spectrum detection system cannot satisfy the effective detection of stealth aircraft targets due to complex Earth background clutter and atmospheric attenuation. Therefore, a detection method that can highlight aircraft targets is urgently needed to enhance stealth aircraft detectability. In this research, a spectrum set consisting of different bandwidths associated with a central wavelength is established. Furthermore, a signal-to-noise ratio of the stealth aircraft is computed using the established spectrum set. Finally, the optimal spectrum is selected according to the maximal signal-to-noise ratio from the spectrum set. Our numerical experiments and simulations further demonstrate that the proposed methodology can substantially strengthen the detection performance of stealth aircraft compared with traditional fixed-spectrum detection systems. This work on detection spectrum optimization paves the way to stealth aircraft detection and opens new vistas in the field of target detection technology.
