Multi‐Task Learning for Airport Surface Surveillance: A Review

Expert Systems, Volume 43, Issue 4, April 2026.
ABSTRACT The rapid growth of air transportation has surpassed the capabilities of traditional airport surveillance methods, such as visual observation and auxiliary equipment (e.g., ADS‐B, MLAT, radar), which struggle to provide all‐area, all‐weather situation awareness.

GRID‐Routing: A Proposal for Massive Traffic Management in Urban Air Mobility

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
Our manuscript introduces a novel grid‐based airspace structure and a physically consistent flight plan model that together enable scalable, conflict‐free trajectory planning for high‐density Urban Air Mobility operations. Extensive validation experiments, including stress‐load scenarios, demonstrate that the proposed framework ensures safe and ...

A Tightly Coupled Fusion Positioning Method Based on Particle Filtering With Effective Particle Neighbourhood Attraction Optimisation

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
To address the limitations of existing wireless and inertial navigation systems, this paper proposes a high‐precision integrated positioning scheme based on particle filtering. The method introduces a high‐weight particle neighbourhood attraction mechanism to solve the common issue of particle degeneracy.

Multistatic Frequency and Polarimetry Adaptive Autofocus for Synthetic Aperture Radar Imaging of a Moving Target

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper presents a multistatic, frequency‐ and polarimetry‐adaptive autofocus algorithm (F‐Pol) for SAR imaging of moving targets undergoing complex, six‐degrees‐of‐freedom (6‐DoF) motion. Building on Localised Threshold Sharpness (LTS), the method exploits agreement across frequency sub‐bands and polarisation channels to improve pulse‐by‐pulse ...

An SI-traceable multilateration coordinate measurement system with half the uncertainty of a laser tracker

, 2023
International audienceWe have validated the performance of a prototype coordinate measurement system based on multilateration by comparing it to a laser tracker, i.e. a well-proven instrument widely used in the industry.

Fingerprint localisation for fine‐scale wildlife tracking using automated radio telemetry

Methods in Ecology and Evolution
Automated radio telemetry systems are one of the most widely applicable methods for tracking wildlife at fine spatiotemporal scales. A growing trend is for these systems to apply large networks of receivers to detect radio signal strength (RSS) from ...

Obstruction-Aware Signal-Loss-Tolerant Indoor Positioning Using Bluetooth Low Energy

Sensors, 2021
Indoor positioning is getting increased attention due to the availability of larger and more sophisticated indoor environments. Wireless technologies like Bluetooth Low Energy (BLE) may provide inexpensive solutions. In this paper, we propose obstruction-

Non‐Coherent Synthetic Aperture Passive Source Localisation

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper addresses the problem of determining, from passive measurements on moving receivers, the position of an unknown source of electromagnetic (or acoustic) waves. This source is assumed to lie on a known surface, and the wave propagation environment is assumed to be free space. This paper addresses the problem in which there are uncertainties in

Multilateral Supervaluationism and Classicality

Journal of Philosophical Logic
Abstract Incurvati and Schlöder (Journal of Philosophical Logic, 51(6), 1549–1582, 2022) have recently proposed to define supervaluationist logic in a multilateral framework, and claimed that this defuses well-known objections concerning supervaluationism’s apparent departures from classical logic.
