Multi-Network TDOA: An opportunity for vessels radiolocation

Abstract

Detection and localization of vessels can be carried out by exploiting the radiolocation approach. Nevertheless, the employment of radiolocalization far from the shore can be limited by the lack of enough receivers to perform a correct multi-lateration of the RF source. In order to solve this gap, mobile assets or base stations from different networks need to be exploited. In particular, within a given search area, a ship could deploy low-cost receivers on drifting buoys, balloons or RPAs, creating a network with several nodes.
