Proportional navigation target tracking
… present a serious threat to today's Navy, a tracking filter which will give superior tracking and trajectory extrapolation when tracking anti-ship missiles is desired. Because most anti-ship missiles use proportional navigation in their guidance systems, it is best to model their motion using …

Target Tracking Via Marine Radar
… of birds towards wind turbines. Radars employ target tracking for identifying the targets (birds) accurately and efficiently. Several methods of tracking were developed to improve the tracking efficiency of the radars over the years. Most widely used tracking techniques are Kalman filter and …

Ground Target Tracking with Multi-Lane Constraint
Knowledge of the lane that a target is located in is of particular interest in on-road surveillance and target tracking systems. We formulate the problem and propose two approaches for on-road target estimation with lane tracking. The first approach for lane tracking is lane identification based …

On particle filters in radar target tracking
… and evaluation of particle filters for radar target track filtering of a maneuvering target, through quantitative simulations and analysis thereof. Target track filtering, also called target track smoothing, aims to minimize the error between a radar target's predicted and actual position. …

Multi-target tracking via mixed integer optimization
Given a set of target detections over several time periods, this paper addresses the multi-target tracking problem (MTT) of optimally assigning detections to targets and estimating the trajectory of the targets over time. MTT has been studied in the literature via predominantly probabilistic …

A Comparison of Multiple-Model Target Tracking Algorithms
There are many multiple-model (MM) target-tracking algorithms that are available but there has yet to be a comparison that includes all of them. This work compares seven of the currently most popular MM algorithms in terms of performance, credibility, and computational complexity. The algorithms to …

Cluster-based target tracking in vehicular ad hoc networks
… potential application for VANET lies in vehicle tracking, where a tracking system is used to visually track a specific vehicle or to monitor a particular area. In this case, and in similar applications such as multimedia content sharing, a large volume of information is required to be transferred …

Partitioned particle filtering for target tracking in video sequences
… filtering algorithm is developed to track moving targets exhibiting complex interaction in a static environment, in a video sequence. The filter is augmented with an additional scan phase, which is a deterministic sequence which has been formulated in terms of the recursive Bayesian paradigm, and …

Cognitive Radar Applied To Target Tracking Using Markov Decision Processes
… This thesis considers an environment with one tracking radar, a single target, and a communications system. The radar-communications coexistence problem is modeled as a Markov decision process (MDP), and reinforcement learning is applied to drive the radar to optimal behavior.
