ABSTRACT
Improving data association process by increasing the probability of detectingvalid data points (measurements obtained from radar/sonar system) in thepresence of noise for target tracking are discussed in this paper. We develop anovel algorithm by filtering gate for target tracking in dense clutter environment.This algorithm is less sensitive to false alarm (clutter) in gate size thanconventional approaches as probabilistic data association filter (PDAF) whichhas data association algorithm that begin to fail due to the increase in the falsealarm rate or low probability of target detection. This new selection filtered gatemethod combines a conventional threshold based algorithm with geometricmetric measure based on one type of the filtering methods that depends on theidea of adaptive clutter suppression methods. An adaptive search based on thedistance threshold measure is then used to detect valid filtered data point fortarget tracking. Simulation results demonstrate the effectiveness and betterperformance when compared to conventional algorithm.
