Maximum likelihood methods for bearings-only target localization
In this work, we develop four maximum likelihood (ML) methods to localize a moving target using a network of acoustical sensor arrays. Each array transmits a direction-of-arrival (DOA) estimate to a central processor, which employs one of the localization techniques. The four ML approaches use different target signal models where the time retardation factor for the target position and the degra...
متن کاملAn Adaptive Tracking Algorithm for Bearings-only Maneuvering Target
To improve the tracking performance of bearings-only maneuvering target, a dynamic and adaptive multiple models (MM) algorithm is proposed in this paper, i.e., the acceleration value of each sub-model of MM structure is adjusted dynamically, unlike the traditional MM method with fixed acceleration levels, by an economic on-line self-constructing neural fuzzy inference network (SONFIN) according...
متن کاملA Rssi Based Localization Algorithm for WSN Using a Mobile Anchor Node
Wireless sensor networks attracting a great deal of research interest. Accurate localization of sensor nodes is a strong requirement in a wide area of applications. In recent years, several techniques have been proposed for localization in wireless sensor networks. In this paper we present a localization scheme with using only one mobile anchor station and received signal strength indicator tec...
متن کاملBearings-Only Localization with NLOS Reflected AoAs
Sensor networks enable the localization of a target (or source) of interest with spatially complementary observations. Current available physical measurements include received signal strength [1], time of arrival [11], angle of arrival (AoA) [6, 7, 10, 13, 19], and so forth. They can be individually or cooperatively utilized in target information extraction. In this paper, we concentrate on loc...
متن کاملSensor Networks for Optimal Target Localization with Bearings-Only Measurements in Constrained Three-Dimensional Scenarios
In this paper, we address the problem of determining the optimal geometric configuration of an acoustic sensor network that will maximize the angle-related information available for underwater target positioning. In the set-up adopted, a set of autonomous vehicles carries a network of acoustic units that measure the elevation and azimuth angles between a target and each of the receivers on boar...
