| Abstract: | The ability to sense mid-air gestures with miniaturised radars embedded in everyday objects opens up new opportunities for interaction. Applications include integration into wearable devices, automotive dashboards, smart furniture, and other components within smart environments. Despite this potential, the lack of studies on how various occluding materials affect gesture recognition performance hinders progress in this area. Previous studies have primarily focused on evaluating only one type of radar signal representation, despite the fact that several other representations exist and were proved effective. To address this, the chapter presents a comparative evaluation of four radar signal representations: In-phase and Quadrature (IQ) representations in the frequency domain and magnitude and range-angle (including both elevation and azimuth components) and range-Doppler. The goal is to assess their robustness against signal distortions introduced by occluding materials. Preliminary results indicate that recognition performance tends to improve with a higher transmission coefficient. Moreover, range-Doppler and range-angle representations exhibit significantly greater robustness to distortion compared to IQ representations |
