Auxiliary Truncated Unscented Kalman Filtering for Bearings-Only Maneuvering Target Tracking

open access: yesSensors, 2017
Novel auxiliary truncated unscented Kalman filtering (ATUKF) is proposed for bearings-only maneuvering target tracking in this paper. In the proposed algorithm, to deal with arbitrary changes in motion models, a modified prior probability density ...

An Unmixing-Based Network for Underwater Target Detection From Hyperspectral Imagery

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Detecting underwater targets from hyperspectral imagery makes a profound impact on marine exploration. Available methods mainly tackle this problem by modifying the land-based detection algorithms with classical bathymetric models, which usually fail to ...

Estimating Shape and Micro-Motion Parameter of Rotationally Symmetric Space Objects from the Infrared Signature

open access: yesSensors, 2016
Shape serves as an important additional feature for space target classification, which is complementary to those made available. Since different shapes lead to different projection functions, the projection property can be regarded as one kind of shape ...

Multiple hypothesis S‐dimensional assignment algorithm for data association of angle‐only sensors with limited fields of view

open access: yesIET Radar, Sonar & Navigation, 2022
This paper focuses on how to obtain globally optimal multisensor data association results under the condition that the number of targets is unknown. This problem is likely to occur in scenarios where the sensors’ fields of view (FoVs) are limited.
