Eco-friendly dual-band AULOS® passive radar for air and maritime surveillance applications

The last results obtained with the Eco-friendly dual-band AULOS® passive radar sensor carried out within the long-term collaboration between Sapienza University of Rome and Leonardo S.p.A. are here reported. Specifically, FM and DVB-T signals are parasitically exploited for air and maritime surveillance applications. A significant effort concerned the development of signal processing techniques to be efficient in both the investigated applications. To this purpose, the recent processing techniques developed by the research group of Sapienza have been applied. We show that the FM-based AULOS is able to detect with great continuity the typical aerial traffic as well as aircrafts with low RCS. In contrast, the DVB-T based sensor can be successfully employed for monitoring vessel of different dimensions both in the proximity of a port that travel during the day. The reported results confirm that the considered sensor can be usefully employed for improving safety and security of public areas, such as airports and harbors, preserving both the landscape integrity and the electromagnetic health of the population.
