Wireless acoustic sensor networks (WASNs) are formed by a distributed group of acoustic‐
sensing devices featuring audio playing and recording capabilities. Current mobile …

A total least-squares (TLS) algorithm is developed for two-dimensional location estimation of
a stationary target by using only passive bearing measurements of the target. This problem …

Node self-localization is a key research topic for wireless sensor networks (WSNs). There
are two main algorithms, the triangulation method and the maximum likelihood (ML) …

This paper investigates optimal sensor placement strategies for angle-of-arrival (AOA)
localization in three-dimensional space. We adopt the A-optimality criterion to determine …

The global positioning system (GPS), which provides ubiquitous location-awareness with a
constellation of satellites, has become an instrumental function of multiple mass-market …

In this paper, we present a location-penalized maximum likelihood (LPML) estimator for
bearing only target localization. We develop a new penalized maximum likelihood cost …

The bearings-only pseudolinear target track estimator is known to suffer from severe bias
problems. This paper presents a bias analysis for the pseudolinear estimator and develops …

The paper presents a new pseudolinear estimator for 3D target motion analysis by a single
moving ownship collecting azimuth and elevation angle measurements. The 3D …

Bearings-only (BO) and Doppler-bearing (DB) target motion analysis (TMA) attempt to obtain
a target trajectory based on bearings and on Doppler and bearing measurements …

The motion of sensors during the measurement period, if not accounted for, can degrade
significantly the localization accuracy. This paper investigates the sensor motion effect for …
