Use of Fixed-Range Noise Radar for Moving-Vehicle Identification

摘要

The Ohio State University ElectroScience Laboratory has built a radar that transmits ultra wideband (UWB) random noise. The received signal is cross correlated with a fixed delay version of the transmitted signal. This produces a radar detection ring at a fixed distance from the radar. As a vehicle or person moves through the detection ring, the range profile and the time dynamics of the moving person/vehicle are traced out. This permits identification, as well as detection of the moving object. We will present a description of the system and show example data. Example signatures will be shown and discussed. The potential for an unattended ground sensor in the foliage penetration and target classification mode will he discussed.
