For conventional missile-borne infrared imaging system is affected by the aerodynamic heating problems, the infrared lateral window imaging method is studied. The aerodynamic heating of the spherical blunt body warhead under different flight conditions is calculated by numerical simulation method. And the analysis shows that the high temperature effect in the non-stagnation point area of the head and side is much smaller than that in the stagnation point area of the front, the incoming Mach number affects the generation of the high temperature area, and the flight angle of attack does not change the extreme value of the high temperature area but affects its spatial distribution. A set of infrared lateral window imaging system is proposed and designed, and the imaging effect with high quality is verified by experiments, which provides a new idea for reducing the adverse effect of aerothermal on missile-borne infrared detection.
