Design and Evaluation of C-Band FMCW Radar System

The design and evaluation of C-Band Frequency Modulated Continuous Wave (FMCW) radar system is presented in this paper. Field Programmable Gate Array (FPGA) board is used to tune the Analog Front End (AFE) of radar system with Digital to Analog Converter (DAC). The IF signal from AFE is then amplified by high precision voltage amplifier circuit and monitored with the help of Analog to Digital Converter (ADC) and FPGA to detect and measure the velocity of the target. The use of the FPGA will allow real-time signal processing. The main purpose of this work is to bring a simplified perspective to design FMCW radar and to carry out a series of laboratory experiments. FMCW radar is capable of providing a better detection of target in motion. The radar design approach and signal processing algorithms are briefed and experimental results are analysed in this paper.
