Passive tracking of a maneuvering target: an adaptive approach
IEEE Transactions on Signal Processing, 1994The problem of target tracking using passive sensors is examined. The target is assumed to execute maneuvers at times unknown to the observer. An adaptive algorithm, which takes into account such maneuvers, is derived using the multimodel partitioning approach.

Passive depth tracking of underwater maneuvering targets
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1985As a parallel extension to the adaptive range tracking of underwater targets described by Moose and Dailey [1], this paper discusses the problem of tracking the depth of a maneuvering target using passive time-delay measurements. The target is free to maneuver in velocity and make random depth changes at times unknown to the observer.

A guidance law for visual tracking of a maneuvering target
2006 American Control Conference, 2006This paper presents an adaptive disturbance rejection control architecture for a flying vehicle to track a maneuvering target using a monocular camera as a visual sensor. The derived guidance law is an acceleration command for the follower and enures range regulation with desired precision. Simulations illustrate the performance of the method.

Fast implementation of ground maneuvering target focusing
Digital Signal Processing, 2019Abstract Ground maneuvering target detection is a hot topic in the applications of synthetic aperture radar (SAR), whereas its focusing performance is severely deteriorated by range migration and Doppler frequency migration during a long integration time.

Resolution and parameters estimations for multiple maneuvering targets
Science China Information Sciences, 2014Resolution and parameters estimations for multiple maneuvering targets in the same range cell is addressed in this work. The low-resolution radar cannot distinguish multiple targets in both distance and angle, but the detection of Doppler frequency variation of the multiple maneuvering targets can be used to resolve this problem.

Optimal Tracking of Maneuvering Targets
IEEE Transactions on Aerospace and Electronic Systems, 1973Maneuvering target motion is modeled by introducing a binary random variable in the target state equation. The optimal estimate is shown to be a weighted combination of two Kalman filter estimates with weights depending on the likelihood ratio for the detection of a maneuver. A tracking scheme is proposed for maneuvering target tracking and illustrated

A filter method for pose estimation of maneuvering target
2004 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2005A filter method is presented for 3D pose (position and orientation) estimation of an arbitrary moving target from a monocular image sequence. Problem considered here is error propagation from image features to pose parameters. To this end, we have derived a combination of two filter schemes. The first filter scheme uses maneuver detection technique, in

Target maneuver detection algorithm
Proceedings of 2005 International Conference on Intelligent Sensing and Information Processing, 2005., 2005Using bearings only information, passive target tracking in under water scenario can be carried out for a target moving at a constant velocity. If the target changes its course or speed or both, the estimated parameters differ with those of actuals. Hence it is usual to find out target maneuver, before the solution diverges completely and appropriately
