A comparison of theoretical, computational, and experimental human electromagnetic scattering at VHF and UHF

Radar-based human detection and classification is a diverse research field that is rich with challenging open problems. There are currently several commercial-off-the-shelf (COTS) computational electromagnetic software packages that have developed human packages specifically for the purpose of radar-based human detection and classification research. In this paper we compare a theoretical and computational state-of-the-art software to recent experimental data on adult and child human subjects using a static radar operating in VHF and UHF. We find that there are unique human-based resonances in the UHF band that may aid researchers in finding a way to classify a general age class and estimate certain physical biometric indexes from radar scattering measurements. We continue the analysis by comparing the regions of the human body that maximally scatter based on frequency selection. We conclude the paper by listing a set of open problems that have been determined based on our papers analysis.
