Abstract
In this paper we propose a novel signal processing architecture for millimeter wave flow velocity radar. FPGA and DSP are combined to make the system more compact while achieving real-time signal processing. We focus on the workflow and software design for DSP, and propose an improved CFAR based on the median absolute difference and quantile for the target characteristics, which improve the detection performance of the radar in dense target condition as well as clutter edge environment. Finally, experiment results show that the signal processing system can work stably and achieve real-time and high-accuracy measurements.
