Moving Target At Constant Velocity Localization Using TOA Measurements From Single Moving Receiver With Unknown Signal Period

IEEE Open Journal of Signal Processing
In this article, we consider using time-of-arrival (TOA) measurements from a single moving receiver to locate a moving target at constant velocity that emits a periodic signal with unknown signal period.

Maximum likelihood localization: When does it fail?

ICT Express, 2016
Maximum likelihood is a criterion often used to derive localization algorithms. In particular, in this paper we focus on a distance-based algorithm for the localization of nodes in static wireless networks. Assuming that Ultra Wide Band (UWB) signals are

Unveiling the Role of Sea‐Ice Loss in Early‐20th‐Century Arctic Warming

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Recent Arctic warming and melting sea ice are iconic features of global warming. Yet, it is unlikely that anthropogenic forcing is solely responsible for these changes. The Early‐20th‐Century Arctic Warming (ETCAW), comparable to the recent one, provides a benchmark for natural climate variability but remains poorly understood.

Multi Detector Fusion of Dynamic TOA Estimation using Kalman Filter

, 2015
In this paper, we propose fusion of dynamic TOA (time of arrival) from multiple non-coherent detectors like energy detectors operating at sub-Nyquist rate through Kalman filtering.

How do CMIP6 Models Represent the Vertical Structure and Chemical Properties of Biomass‐Burning Aerosols Emitted in Central Africa?

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract CMIP6 climate models have difficulties representing the strong absorption properties of biomass‐burning aerosols (BBA) over the Southeast Atlantic and the associated direct forcing. This study takes advantage of unique in situ and remote sensing observations to evaluate the vertical profile and chemical composition of BBA, which are key ...

Distributed Cooperative Localization in Wireless Sensor Networks without NLOS Identification [PDF]

, 2014
In this paper, a 2-stage robust distributed algorithm is proposed for cooperative sensor network localization using time of arrival (TOA) data without identification of non-line of sight (NLOS) links.

The Source Brightness Distribution of Terrestrial Gamma‐Ray Flashes From the ALOFT Flight Campaign

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Terrestrial Gamma‐ray Flashes (TGFs) are naturally occurring phenomena that consist of bursts of gamma radiation associated with thunderclouds. Measurements of TGFs have been predominantly based on satellite instruments due to the significantly larger observation area compared to ground measurements. Due to atmospheric attenuation of the gamma

Artificial Neural Network for Location Estimation in Wireless Communication Systems

Sensors, 2012
In a wireless communication system, wireless location is the technique used to estimate the location of a mobile station (MS). To enhance the accuracy of MS location prediction, we propose a novel algorithm that utilizes time of arrival (TOA ...
