Zhichao Zhu, Wenhui Zhang, Jizhen Ma, Yujia Lu · 2024
This study introduces a testbed for real-time millimeter wave (mmWave) radar system evaluation, overcoming the limitations of traditional embedded chips and DSP techniques. We developed a specialized software library and leveraged an FPGA with high-speed Ethernet alongside an edge computing device for efficient signal capture and processing. The system delivers high-resolution range profiling with a bit error rate below 10−6at 20 Hz refresh rate and performs vital sign monitoring with less than 128ms latency at 10 Hz refresh rate. Comparative analysis with TI’s official library validates the system’s reliability and efficiency.
