Abstract
The paper presents a comparative analysis of recent collision avoidance and real-time path planning algorithms for ships. Compared methods utilize radar remote sensing for target ships detection. Different recently introduced approaches are briefly described and compared. An emphasis is put on input data reception using a radar as a remote sensing device applied in order to detect moving obstacles such as encountered ships. The most promising methods are highlighted and their advantages and limitations are discussed. Concluding remarks include proposals of further research directions in the development of collision avoidance methods utilizing radar remote sensing.
Highlights
An autonomous ship can be defined as a marine craft, equipped with sensors used to obtain information about the environment, that is characterized by automated navigation, propulsion and auxiliary systems and applies advanced control algorithms to operate without human intervention
In 2021 [53], a path planning method based upon a differential evolution (DE) algorithm was proposed, assuming that data concerning target ships are available from navigational aids such as Automatic Radar Plotting Aid (ARPA) and Automatic Information System (AIS)
The aim of the paper was to present a comprehensive review of different collision avoidance and real-time path planning methods for ships, with a concentration on radar remote sensing and the usage of other sensors for target ships’ detection and tracking
Summary
An autonomous ship can be defined as a marine craft, equipped with sensors used to obtain information about the environment, that is characterized by automated navigation, propulsion and auxiliary systems and applies advanced control algorithms to operate without human intervention As it can be stated based upon the above mentioned description of an autonomous vessel, an important component of such vehicle is the Autonomous Navigation System (ANS). The aim of the research presented in this paper was to conduct a comprehensive review of recent collision avoidance and real-time path planning methods for ships applying radar remote sensing.
