Tracking of a Manoeuvering Target Ship using Radar Measurements
Indian Journal of Science and Technology, 2015 For on sea water measurements of range on bearing in naval operations various types of Kalman filters including extended Kalman filter have been used. In this paper ,input estimation techniques applied normally to in air applications are applied to on sea measurements using chi – square distribution random sequence residual techniques.

A Bidirectional Imitation-Learning Framework for Real Time Trajectory Planning in Automatic Berthing [PDF]
TransNavThis paper presents a bidirectional imitation-learning framework for AIS-based real-time trajectory planning in automatic berthing. The framework connects a ship’s current state with a prescribed terminal berthing condition by using two imitation ...

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.(1) A dynamic decision‐making model for ship berthing is proposed to provide real‐time assistance to shipmasters and pilots. (2) The proposed model considers the kinematic parameters related to ship berthing. (3) The proposed model employs a structured three‐layer fuzzy inference system to derive berthing decision‐making results. ABSTRACT Ship berthing

Research on The Prediction of Congestion Risk of Ship Traffic Flow in Vulnerable Waterways
IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.Vulnerable inland waterways frequently suffer from vessel traffic congestion. This study proposes an FCM clustering combined with stacking ensemble learning model to identify and predict navigation risk levels based on AIS trajectory data. The experimental results prove that the proposed method outperforms traditional single machine learning models and

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This study addresses the obstacle avoidance problem of a multi‐thruster AUV in unfamiliar environments by combining in‐place steering with single‐beam ranging. An optimised Vector Field Histogram algorithm is designed to enable real‐time heading decisions using the collected multi‐directional distance data.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper investigates the moving target detection under the low earth orbit navigation augmentation (LEO‐NA) signal‐based PR (LNAS‐PR) system, which utilises the LEO satellite with navigation augmentation capability as the illuminator. By jointly considering the target's motion and electromagnetic scattering characteristics, this paper proposes a ...

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Ship–bridge pier collisions signify a serious risk to structural integrity and construction health and safety during bridge construction phases where structural redundancy is limited. This study develops a hybrid finite element–machine learning (FE–ML) replacement framework for rapid prediction of collision consequence severity under different maritime
