In today battlefield multi-sensors installed on naval ship are acquiring too much information. Information is used through naval combat system to improve reaction capability to threat more quickly and precise. For acting to threat, we have to make a decision whether same ones what each target from multi sensor and execute track fusion according to result of judgment. We predicted and estimated the target state based on dynamic information using data association filter so made valid measurement area what is assumed that track exists.
Multisensor Fusion pp Cite as. Multitarget tracking MTT here after deals with state estimation of an unknown number of moving targets. Clutter is generally considered as a model describing false alarms. Its spatio-temporal statistical properties are quite different from target ones which render possible the separation of target tracks on the one hand and clutter model on the second. To perform multitarget tracking the observer has at its disposal a huge amount of data, possibly collected on multiple sensors . Elementary measurements are receiver outputs; e.

Probabilistic data association techniques for target tracking in clutter Abstract: In tracking targets with less-than-unity probability of detection in the presence of false alarms FAs , data association-deciding which of the received multiple measurements to use to update each track-is crucial. Most algorithms that make a hard decision on the origin of the true measurement begin to fail as the FA rate increases or with low observable low probability of target detection maneuvering targets. Instead of using only one measurement among the received ones and discarding the others, an alternative approach is to use all of the validated measurements with different weights probabilities , known as probabilistic data association PDA. This paper presents an overview of the PDA technique and its application for different target tracking scenarios.
This paper is to survey and put in perspective the working methods of multi-target tracking in clutter. This paper includes theories and practices for data association and related filter structures and is motivated by increasing interest in the area of target tracking, security, surveillance, and multi-sensor data fusion. It is hoped that it will be useful in view of taking into consideration a full understanding of existing techniques before using them in practice. Download PDF. Article Info.

Performance indexes obtained in idealized simulated scenarios are the primary source of data for evaluating different target tracking algorithms in most researches presented in the literature. Despite the convenience of simulation, ultimate evaluation of a tracking algorithm must be made in real scenarios. Unfortunately, real radar measurements as well as accurate aircraft position, necessary for calculating tracking errors, are not easily available.
