Target Detection Using a GPS Forward-Scattering Radar

The Global Positioning System (GPS) allows the accurate positioning of an object using satellite signals. There are a lot of applications of this technology in many scientific fields all over the world. The paper focuses on scientific issues related to new application of GPS technology using the effect of Forward Scattering (FS) of electromagnetic waves to detect targets by their GPS radio shadows. The aim of the paper is to make experimental studies of GPS radio shadows of vehicle targets irradiated by GPS signals and to develop algorithm for automatic detection of the shadows of these targets. In this paper, we offer an original approach for using of CFAR techniques for detection of moving targets from GPS radio shadows. The results show that from GPS radio shadows of different objects can be extracted information for classification of objects aimed at transport management or security of zones.
