In this paper, the authors present a measurement testbed for OFDM radar which uses USRPs as a front-end. The resulting system, using two USRPs and a laptop, requires little power and can thus be easily installed in vehicles to perform measurements for car-to-car or car-to-infrastructure applications. As an example, they show how signals parametrized according to the IEEE 802.11a/p standards can be enhanced by radar functions without any additional spectrum usage and only a little extra signal processing.
