Signal selective DOA tracking for multiple moving targets

A new algorithm for signal selective tracking of the directions-of-arrival (DOA’s) of multiple moving targets with an array of passive sensors is presented. A new method based on the principles of maximum likelihood estimation and cyclostationarity is used to generate initial angle estimates which, in turn, are refined by a Kalman filter. Source angle dynamics are used to achieve correct data a...

Multiple Moving Targets Tracking Research in Cluttered Scenes

Traditional particle filter (PF) will have bad effect when the target’s color is similar to the background or the target is blocked, and an improved tracking algorithm is presented in the framework of PF and DSmT. According to the location cue, a new tracking approach is given to establish the model of multiple moving targets based on information fusion. Experimental results demonstrate that th...

Tracking Multiple Moving Targets using a Camera and Laser Rangefinder

We propose a target tracking system based on a camera and laser rangefinder. Two trackers have been developed: a laser-based tracker and a vision-based tracker. They detect moving or bright-colored targets, and report the positions of the targets in a coordinate system rigidly attached to the sensors. Both trackers have been implemented and tested with stationary sensors embedded in an office e...

Optimal Observer Path Planning For Bearings-Only Moving Targets Tracking Using Chebyshev Polynomials

In this paper, an optimization problem for the observer trajectory in the bearings-only surface moving target tracking (BOT) is studied. The BOT depends directly on the observability of the target's position in the target/observer geometry or the optimal observer maneuver. Therefore, the maximum lower band of the Fisher information matrix is opted as an independent criterion of the target estim...
