With over half a centurys signature management experience, Saab's high competence and expertise are applied to every solution we produce. The spectral compatibility is ensured by leveraging the wavelength difference. In this paper, multispectral camouflage is demonstrated for the visible, mid-infrared (MIR, 35 and 814m), lasers (1.55 and 10.6m) and microwave (812GHz) bands with simultaneous efficient radiative cooling in the non-atmospheric window (58m). As a result, different application-specific constructions can be used without compromising the camouflage effect. Multi-band middle-infrared-compatible camouflage with thermal management via simple photonic structures. However, a combination of advanced detectors operating in different wavelength bands (e.g., visible to MWIR camera15, SAR, and IR combination16) developed in recent years entails a compatible camouflage among different spectral bands, i.e., multispectral camouflage17,18,19,20,21. 14, 328 (2003). Here are some interesting facts about ULCAS you may not already know. PubMed Mater. Other heat transfer channels, including conduction, side convection, and wire convection/radiation are regarded as parasitic loss, which are identical for SE and Cr at the same temperature. It gives instructors the tools to train prospective signature management operators. Commun. According to the Stefan-Boltzmann law, the thermal radiation intensity is proportional to the fourth power of the surface temperature; therefore, reduction of the surface temperature is desired for IR camouflage32,33,34,35, especially for the military objectives with high surface temperature (e.g., converging nozzles of aircraft (~950K)36, tailpipe of aircraft (~740K)37, and funnels of naval ships (~680K)38).
