Abstract

This paper presents a methodology for measuring the radar cross-section (RCS) of a target that scatters power from multiple points on its surface, in the context of joint communication and sensing (JCAS). By leveraging the fine resolution of millimeter-wave and sub-terahertz radar systems, the proposed approach can estimate the location of multiple scattering points on the target and compute their respective RCS values. This enables enhanced target classification and recognition, essential for high-resolution applications such as gesture recognition, indoor localization, and biomedical sensing. A comprehensive calibration procedure ensures accurate RCS estimation by incorporating techniques such as calibration against a metal sphere, background subtraction, and super-resolution. The paper details the use of a 28.5 GHz channel sounder to illustrate the proposed method, highlighting its application in a human gesture JCAS scenario. The results demonstrate the accuracy and potential of this method for advanced radar applications in various fields.
