Abstract
Focusing on detecting the illegal behavior of dumping dredged sediments by dredgers at ports, a sensor network composed of two acoustic sources and several passive sensor arrays is proposed in this...
Highlights
Marine transportation, in its long history, has a close relationship with the maritime countries’ development
In order to meet the need of the background, we develop a new approach in the article based on marginal spectrum of Hilbert–Huang Transform (HHT) for local sensors to detect the event
Thereby, we introduce a scanning window by which we can sacrifice the performance of Pf for higher Pd, that is, make a tradeoff between Pf and Pd
Summary
In its long history, has a close relationship with the maritime countries’ development. Dredgers often dump dredged sediments on the road during their transportation instead of to the prescribed disposal site. International Journal of Distributed Sensor Networks monitoring recorder for marine wastes dumping.[2] By contraries, ship-equipping-free approaches could work without equipping any devices on dredgers. If a dredger is detected having flowing sediments on its way to the disposal site, it is declared to dump dredged sediments illegally. This involves a subject known as underwater target detection.
