چکیده
Abstract For the bearings-only target tracking for single array, performance of extended kalman filter algorithm in cartesian coordinates and modified polar is studied. The result shows that more general than coordinates. In addition, these two algorithms decreases with an increase azimuth measurement error.

Improved Bearings-Only Multi-Target Tracking with GM-PHD Filtering
In this paper, an improved nonlinear Gaussian mixture probability hypothesis density (GM-PHD) filter is proposed to address bearings-only measurements in multi-target tracking. The proposed method, called the Gaussian mixture measurements-probability hypothesis density (GMM-PHD) filter, not only approximates the posterior intensity using a Gaussian mixture, but also models the likelihood functi...
متن کاملAn Adaptive Tracking Algorithm for Bearings-only Maneuvering Target
To improve the tracking performance of bearings-only maneuvering target, a dynamic and adaptive multiple models (MM) algorithm is proposed in this paper, i.e., the acceleration value of each sub-model of MM structure is adjusted dynamically, unlike the traditional MM method with fixed acceleration levels, by an economic on-line self-constructing neural fuzzy inference network (SONFIN) according...
متن کاملBearings-Only Tracking in the Plane
It is known that the conditional probability density function for the general filtering problem can be represented as a path integral. This representation is the basis of a new finite dimensional recursive filter which is applied to bearings only tracking. The filter computes an approximation to the density for the target position conditional on the measurements. The approximation is accurate p...
متن کاملOptimal Sensor Trajectories in Bearings-Only Tracking
We consider the problem of determining sensor trajectories in the bearings-only tracking of an uncertain target. This work differs from previous research in that we allow the target dynamics to be both uncertain and random; and also consider multi-sensor scenarios. The basis of our technique is to control a measure of estimation error based on the Posterior Cramér-Rao lower bound (PCRLB), and w...
متن کاملOptimal 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...
