Paper Title
Design and Implementation of A Low Cost Fmcw Radar with Configurable Signal Processor for Human Movement and Breathing Detection

In this paper, a portable low cost, and low power consumption FMCW radar was designed and implemented for human detection and breathing rate estimation. The operating bandwidth is 200MHz centered at 4.8GHz. The radar is working in indoor and outdoor scenarios. The radar was implemented using a high gain transmit and receive antenna, high selectivity bandpass filter, good rejection baseband lowpass filter, and power divider with minimum losses. Furthermore, the signal processor is implemented on a Xilinx Artix-7 Field Programmable Gate Array (FPGA) using a simple architecture. Also, the radar digital signal processor parameters are manually reconfigurable during run time operation. Keywords— FMCW, Radar, Human, Breathing, Movement Detection
