Maritime Moving Target Indication and localisation with GNSS-based multistatic radar: Experimental proof of concept

Abstract

This paper focuses on the feasibility of using Global Navigation Satellite System (GNSS) as the transmitters of opportunity in a passive maritime surveillance radar, mainly for the applications of maritime Moving Target Indication (MTI), as well as the target localization. This can be achieved using multistatic GNSS acquisitions with multiple satellites and a single receiver, and applying multilateration techniques. For an experimental verification, the target localisation concept was applied to practical maritime measurement conducted with GNSS-based radar test bed and bistatic ranges of one target for two different satellites successfully gained. The experimental localisation results have a high coincidence with the ground truth and confirm the system concept.
