An Efficient Ground Manoeuvring Target Refocusing Method Based on Principal Component Analysis and Motion Parameter Estimation

Remote Sensing, 2020
Refocusing ground manoeuvring targets with complex motions in synthetic aperture radar (SAR) remains a challenging objective because of the large range of cell migration (RCM) and time-varying Doppler frequency modulation (DFM).

Numerical Analysis on the Scale Effect of a Free-Running Ship’s Manoeuvring Characteristics

Journal of Marine Science and Engineering
This study focuses on the manoeuvring characteristics of model- and full-scale ships. Various methods, including free-running model tests (FRMTs), computational fluid dynamics (CFD), and theoretical approaches, were employed to estimate ship manoeuvring ...

Data Acquisition in a Manoeuver Auto-negotiation System [PDF]

TransNav, 2015
Typical approach to collision avoidance systems with artificial intelligence support is that such systems assume a central communication and management point (such as e.g. VTS station), usually located on shore.

Application of an expert system shell in the preliminary design of offshore supply vessels [PDF]

, 1993
This paper presents the application of expert system programming in preliminary ship design with particular emphasis on offshore supply vessels. Instead of using one of the conventional programming expert system languages, the system is developed using ...
