Abstract

A Doppler OFDM radar system is aimed at obtaining radial velocity and distance detection results from the target. This paper reports the implementation of a Doppler OFDM radar system on an SDR platform. The design of the radar system with math script is fed into LabVIEW Communication serving as processing software. The system uses USRP NI- 2943R as a device for generating and receiving OFDM doppler radar signals that work in the S-Band. The test results show that to improve the detection result the number of sub carriers and OFDM symbols generated must be taken into account. From the test, relative errors of 5.6% for detection of radial rate and of 16.8% for detection distance are obtained with 40 MHz bandwidth. An increase in sample rate proportional to the value of OFDM signal bandwidth on USRP greatly affects the performance of systems.
