Spacecraft formation-flying using potential functions [PDF]

open access: yes, 2008
A group of small spacecraft able to change their relative position and attitude through the use of the potential function method is discussed. The spacecraft shapes, sizes and manoeuvring capabilities are not identical, although all are assumed to ...

ATC Level Tactical Manoeuvring during Descent for Mitigating Impact of ADS-B Message Injection Cyber Attack

open access: yesEngineering Proceedings, 2022
To reduce delays caused by an ADS-B Message Injection attack, we propose an Air Traffic Control (ATC) level tactical manoeuvring framework for maintaining safe flight trajectories while reducing diversion from the original trajectory during the descent ...

Novel priori-knowledge-free manoeuvring target-tracking method

open access: yesThe Journal of Engineering, 2019
In the past few decades, many manoeuvring target-tracking methods have been proposed. However, most of these methods require some priori knowledge about the target, which is hard to obtain in many scenarios.

Bearings-Only Target Tracking with an Unbiased Pseudo-Linear Kalman Filter

open access: yesRemote Sensing, 2021
In bearings-only target tracking, the pseudo-linear Kalman filter (PLKF) attracts much attention because of its stability and its low computational burden.

Wave effects on the turning ability of an ultra large container ship in shallow water [PDF]

open access: yes, 2019
The influence of waves on ship behaviour can lead to hazardous scenarios which put at risk the ship, the crew and the surroundings. For this reason, investigating the effect of waves on manoeuvring is of relevant interest.

Precise motion compensation method in terahertz ISAR imaging based on sharpness maximization

open access: yesElectronics Letters, 2022
According to the characteristics of the manoeuvring targets and the superiorities of Terahertz Inverse Synthetic Aperture Radar (THz‐ISAR), a precise motion compensation method based on image sharpness maximization for manoeuvring targets in the ...

Distributed tracking with sequential Monte Carlo methods for manoeuvrable sensors [PDF]

open access: yes, 2006
Nonlinear distributed tracking for a single target is addressed in this paper. This problem consists of tracking a target of interest while moving the sensors to `best' positions according to an critera appropriate for the problem.

Sparse long‐time coherent integration‐based detection method for radar low‐observable manoeuvring target

open access: yesIET radar, sonar & navigation, 2020
Low-observable manoeuvring target detection is a challenging problem for radar signal processing, due to the complex environment, target manoeuvrability, limited observation time etc.

Evaluating air emission inventories and indicators from cruise vessels at ports [PDF]

open access: yes, 2017
This paper provides an estimation of air emissions (CO2, NOX, SOX and PM) released by cruise vessels at the port level. The methodology is based on the Bfull bottom-up^ approach and starts by evaluating the fuel consumed by each vessel on the basis of
