This work discusses methods and experimental results on passive radar detection of moving ships using navigation satellites as transmitters of opportunity. The reported study highlights as the adoption of proper strategies combining target motion compensation and track-before-detect methods to achieve long time integration can be fruitfully exploited in GNSS-based passive radar for the detection of maritime targets.

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.
