Abstract
This paper presents an SDR (Software-Defined Radio) implementation of an FMCW (Frequency-Modulated Continuous-Wave) radar using a USRP (Universal Software Radio Peripheral) device. The tools used in the project and the architecture of implementation with FPGA real-time processing and PC off-line processing are covered. This article shows the detailed implementation of an FMCW radar using a USRP device with no external analog devices except for one amplifier and two antennas. The FMCW radar demonstrator presented in the paper has been tested in the laboratory as well as in the real environment, where the ability to detect targets such as cars moving on the roads has been successfully shown.
