Target tracking in maneuver centered coordinates
Proceedings of the 1988 IEEE National Radar Conference, 1989Aircraft targets normally maneuver on circular paths which has led to tracking filters based on circular turns. The authors introduce a new coordinate system to track circular maneuvers with a simple Kalman filter. When the maneuver is detected the tracker switches to a polar coordinate system located at the center of the maneuver.

An analysis of tracking gate for maneuvering targets
Proceedings of the 41st SICE Annual Conference. SICE 2002., 2003It is important for a maneuvering target tracking to decide an proper gatesize parameter d in clutter environment. There are 2 problems to set gatesize parameter. One of the problems is that d set for a target in cluttered environment, the other is that d set for a maneuvering target.

Research on Navigation Based on Target Maneuver
2019 14th International Conference on Computer Science & Education (ICCSE), 2019The performance of PN and APN was compared in this paper, especially the guidance system with acceleration saturation. The results show that the acceleration of the missile using PN must be 5 times higher than that of the target in order to intercept successfully, however, the acceleration using APN need only 2 times than target maneuver and can gain ...

A New Tracking Algorithm for Maneuvering Targets
2020In 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 ...

Accuracy Study for a Piecewise Maneuvering Target with Unknown Maneuver Change Times
IEEE Transactions on Aerospace and Electronic Systems, 2014This 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.

Renewal models for maneuvering targets
IEEE Transactions on Aerospace and Electronic Systems, 1995Most 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.

Target visibility for multiple maneuvering target tracking
SPIE Proceedings, 2015We 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 ...

Sequential detection of target maneuvers
2005 7th International Conference on Information Fusion, 2005This 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.

Detection Of Maneuvering Target Tracks
SPIE Proceedings, 1985This 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), 2015The 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
