Abstract

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.

VHF和UHF人体电磁散射的理论、计算和实验比较

基于雷达的人体检测与分类是一个多元化的研究领域，充满了具有挑战性的开放问题。目前有几个商用现货(COTS)计算电磁软件包开发了人类软件包，专门用于基于雷达的人类检测和分类研究。在本文中，我们比较了理论和计算的最先进的软件，最近的实验数据在成人和儿童人类受试者使用静态雷达在甚高频和超高频操作。我们发现，在UHF频段中存在独特的基于人类的共振，这可能有助于研究人员找到一种方法来分类一般年龄类别，并从雷达散射测量中估计某些物理生物特征指标。我们通过比较基于频率选择的最大散射的人体区域来继续分析。我们通过列出一组基于论文分析确定的开放问题来结束本文。
