WebbAs a consequence, it is clear that σQ is a property that (approximately) characterizes a specific target, not the radar system and/or its interaction with the target. In this case, the simulation of σQ for the proposed design of a vehicle will provide a good estimate of its “radar invisibility.” WebbThe high demand for unlicensed spectrum mandates the use of higher frequencies, such as the 60 GHz band, where large amounts unlicensed bandwidth exists. In this paper, the re-sults from Power Azimuth Spectrum (PAS) measurements in a home and an office environment are presented with a view of revealing the amount of scattering power at …
