Accurate multi-target surveillance system over wide areas

Abstract

The article presents an accurate system for surveillance purposes of multiple targets in wide areas. The surveillance system is based on a GB-ROSAR (Ground-Based-Rotating Synthetic Aperture Radar). It is a fixed radar with the ability of obtaining images by synthesizing the radiating aperture by a circular movement of the antenna. The prototype makes use of FM-CW (Frequency-Modulated Continuous-Wave) signals, operating in millimeter wave bands. The system has been developed with low cost devices. The objective of this work is to show, through simulations and experimental results, the real possibilities of this type of systems in the setting of precise surveillance of several targets simultaneously over wide areas. This study contains the design and construction of the proposed surveillance system, the implemented signal processing, the obtained results and its interpretation, and the conclusions about this work.
