DVB-S based Passive Radar for Short Range Security Application

DVB-S based passive radars have been shown to effectively detect small RCS targets in the short-range, providing high range and velocity resolution. However, the critical infrastructure protection application also requires: (i) an adequate angular measurement accuracy, to localize to targets in the Cartesian Plane, and (ii) a real-time processing capability, able to provide prompt and frequently updated monitoring. This work presents an architecture and a processing scheme able to provide these characteristics and it demonstrates it by fielding, within Sapienza University of Rome, a low-cost COTS-based PCL receiver. The analysis of the experimental results validates the selected solution and demonstrates its high effectiveness.
