IET Radar, Sonar &Navigation, Volume 17, Issue 2, Page 153-178, February 2023., 2023 Abstract A multi‐function radar is designed to perform disparate functions, such as surveillance, tracking, fire control, amongst others, within a limited resource (time, frequency, and energy) budget. A radar resource management (RRM) module within a radar system makes decisions on prioritisation, parameter selection, and scheduling of associated ...

The Modern Law Review, Volume 86, Issue 1, Page 238-248, January 2023., 2023 The voidability of a contract procured by ‘economic duress’ is now well‐established, but the precise boundaries of the doctrine remain contested. In Pakistan International Airlines Corp v Times Travel (UK) Ltd [2021] UKSC 40, the Supreme Court confronted the longstanding controversy as to whether a threat to perform a lawful act can provide grounds for

IET Radar, Sonar &Navigation, Volume 16, Issue 11, Page 1881-1894, November 2022., 2022 Abstract The Gaussian mixture probability density (GM‐PHD) filter has become a popular approach to solve the multiple‐target tracking (MTT) problem because it can effectively and efficiently estimate the number of targets and target states that change over time from noisy measurements.

EDA: New System for Improving Navigation Standards (Totem Plus) [PDF]
TransNav, 2017 EDA is a tool for auditing vessel?s performance that helps installing strict safety navigation standards on ships. The practice of investigating every near-miss event is common in aviation, but unheard of in the maritime industry. At the same time, major

IET Electrical Systems in Transportation, Volume 12, Issue 2, Page 89-101, June 2022., 2022 Abstract Ship motions affect the propulsion system, which causes fluctuations in the power system. Mutually, the power system variations impact the ship velocity by generating speed changes in the propeller. Therefore, interconnecting the ship hydrodynamic and power system has paramount importance in designing and analysing an all‐electric ship (AES ...

Intelligent Control for Ship Manoeuvering
Journal of Advanced Research in Applied Mechanics, 2020 In ship manoeuvering, the only two actuators are rudder and propeller revolution for the whole system. Therefore, by controlling these two for a designated purpose, automation in ship manoeuvering could be established. Classical control system like PID for track keeping or course changing has widely been used by on-board autopilot system.

IET Radar, Sonar &Navigation, Volume 16, Issue 5, Page 912-923, May 2022., 2022 Abstract In forward‐looking imaging, left‐right Doppler is ambiguous and cross‐range resolution is limited by real aperture, which result in traditional synthetic aperture radar imaging methods no longer applicable. Besides, the impact of three‐dimensional acceleration on an over‐complete dictionary matrix and sparse reconstruction kernel is not ...

IET Cyber-Systems and Robotics, Volume 4, Issue 1, Page 51-60, March 2022., 2022 Abstract This study investigates the integral line of sight (ILOS) path‐following control problem of surface vehicles whose dynamics feature external disturbances, model uncertainties, and actuator dead zones. First, introducing the ILOS guidance law, the path‐following control problem is converted to stabilising a 2nd order nonlinear system ...

Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022 A novel real‐time collision avoidance method for autonomous ships based on modified velocity obstacle (VO) algorithm and grey cloud model is proposed. A typical VO algorithm is used to judge whether there is a collision risk for ships in the potential collision area (PCA).
