Analysis of the Integration Applicability of Active Infrared Stealth Technology under Radar Stealth Design Constraints

To address the requirements of multispectral stealth, this study examines the applicability of infrared (IR) stealth techniques based on surface temperature control under radar stealth design constraints, including radar-absorbing materials (RAM) and low-RCS structures. Thermal simulations and infrared image analyses show that RAM induces delayed thermal response and uneven surface temperatures, which increase IR detectability. These effects are mainly due to the inferior thermal properties of RAM compared to metals. Based on these findings, the study proposes design directions for integrated IR–RF stealth systems, focusing on multilayer surface structures and adaptive thermal control strategies.
