Accuracy Study for a Piecewise Maneuvering Target with Unknown Maneuver Change Times

IEEE Transactions on Aerospace and Electronic Systems, 2014
This article presents advances in determining the maximum estimation accuracy, as well as estimating the state for a piecewise maneuvering target with unknown maneuver change times, using passively obtained azimuth (bearings only), azimuth rate, and range measurements.

A New Tracking Algorithm for Maneuvering Targets

2020
In target tracking for radar with Kalman filter, the process noise covariance matrix is usually selected experientially and assumed to remain unchanged throughout the tracking process. Although this method is effective on steady moving targets, in some practical situation, especially in the case of large maneuvering targets, we will meet some ...

Target visibility for multiple maneuvering target tracking

SPIE Proceedings, 2015
We present a recursion of the probability of target visibility and its applications to analysis of track life and termination in the context of Global Nearest Neighbour (GNN) approach and Probability Hypothesis Density (PHD) filter. In the presence of uncertainties brought about by clutter; decisions to retain a track, terminate it or initialise a new ...

Renewal models for maneuvering targets

IEEE Transactions on Aerospace and Electronic Systems, 1995
Most model-based tracking algorithms represent the temporal dynamics of a maneuver acceleration with a Markov process. The sample paths so generated may not be plausible. A renewal process model is shown to be more realistic, but a tracker based upon it is seen to be more complicated to implement.

Detection Of Maneuvering Target Tracks

SPIE Proceedings, 1985
This paper presents a new technique for the detection of moving target tracks, where those tracks are linear paths or segments of circles[1,2]. The images used as input represent a time-varying sequence of noisy satellite images of terrain and a moving target(s).

A method of tracking maneuver target

The 27th Chinese Control and Decision Conference (2015 CCDC), 2015
The problem of tracking maneuver target has been widely researched in the whole world and a good tracking approach may help to gain the advantage of the battlefield and to track the target effectively. A common flow of process the problem has been provided and a formulation of the tracking problem has been discussed from a different perspective in this

Sequential detection of target maneuvers

2005 7th International Conference on Information Fusion, 2005
This paper addresses target maneuver onset detection based on sequential statistical tests. Cumulative sums (CUSUM) type and Shiryayev sequential probability ratio (SSPRT) tests are developed by using a likelihood marginalization technique to cope with the difficulty that the target maneuver accelerations are unknown.

Visual Tracking of a Maneuvering Target

Journal of Guidance, Control, and Dynamics, 2006
This paper presents an acceleration-command generation and its implementation for an aerial vehicle in the problem of visual target tracking, when the target is free to make any maneuver with arbitrary but otherwise bounded acceleration. The acceleration command is generated by an adaptive disturbance rejection control algorithm that uses only visual ...

Tracking of a maneuvering underwater target

2011 International Symposium on Ocean Electronics, 2011
This paper elaborates a technique for improving the performance of a sensor network based system for tracking an abruptly maneuvering under water target. The results of tracking estimates of a maneuvering target may vary owing to various noises and interferences such as sensor errors and environmental noises.

Ensemble of KalmanNets for Maneuvering Target Tracking

2024 27th International Conference on Information Fusion (FUSION)
Tracking a maneuvering target requires the modeling of the target's movements by multiple pre-defined mathematical models. However, the uncertainty in the target's dynamics can lead traditional model-based (MB) tracking algorithms to significant performance degradation when model mismatch occurs.
