Gray Track Correlation Algorithm Based on the Polar Coordinate Interval Numbers
Huaiwei Zhang · Ship Electronic Engineering · 2012
The problem of track correlation in the presence of time-variable system bias in a radar network is researched in this paper.Staring from the track uncertainty,a method that a gray area can be directly expressed into several polar coordinate parameter interval numbers is proposed on the basis of the analysis for the impact from the bias.And a correlation model on gray interval numbers is established to realize the goal that two bias tracks can be related to each other without registration.Results of simulation show that,this algorithm is effective and has a good performance under worse circumstances.
