Abstract

In the classical radar processing chain detection and tracking are separate, consecutive processes. In the case of the large amount of detection the number of false alarms and in consequence the number of false plot-to-track associations highly increase. In such case it can be used one of the Track-Before-Detect (TBD) algorithms that connects the detection and tracking into one process. An important part of such method is the plots preselection during the track forming process which is related to track constraints. One of the simplest method is gating that eliminates unlikely observation-to-track pairings. The basic gates in the two-dimensional space are the rectangular one and elliptical one. In the article the comparison of the use of both shapes is presented. The number of false associations and the gating computational complexity is considered.
