HAR UWB RADAR DATASET

In this work, we employed the XeThru X4M300 radar to generate and receive Ultra-Wideband (UWB) signals for human activity recognition in indoor environments. The XeThru X4M300 pulse-Doppler radar module operates at a configurable carrier frequency of either 7.29 GHz or 8.42 GHz, providing a high-resolution solution specifically suited to indoor applications such as human presence monitoring, motion tracking, and security. Its UWB pulse transmission enables enhanced range resolution, crucial for accurately distinguishing between multiple human activities. Key attributes of X4M300 radar include its adaptability for customized settings, such as adjustable detection range, frame rate, pulse count per step, and sweep iteration. These configurable parameters allow precise optimization for various applications, maximizing signal clarity and robustness. Additionally, the radar module is equipped with digital down-conversion, advanced filtering, and data rate optimization capabilities, enhancing both signal processing efficiency and data fidelity, which are essential in radar-based human activity recognition tasks where real-time, high-quality data capture is critical.
