Design, implementation and first experimental results of an X-band ubiquitous radar system

This paper presents the design and first experimental results of a ubiquitous frequency modulated continuous wave (FMCW) radar system demonstrator, working at 8.75 GHz (X band). This system, which main application is the surface surveillance, is currently under its field-testing phase. This article presents the demonstrator and describes its main blocks, with particular attention to the receiving hardware. Subsequently, it focuses on signal acquisition and digitization, to later explain the offline coherent signal processing carried out with the captured data. After this, the document introduces the chosen scenario for the first field tests, and shows the first results of the offline processing, illustrated with Range-Doppler matrices and detection figures. Finally, the paper introduces future work lines, including the development of a radar data processor taking advantage of the strong range-speed association achieved.
