Abstract

A target tracking system is represented as a component of a radar system, or part of a command and control system (C2) which associates successive detections of a given target, by identifying the same object in different positions over time, and associating the offset in a single trace. Because of its ability to detect targets beyond earth curvature, OTH radars have specific monitoring condition in relation to the displacement of targets that requires a tracking system able to process multiple different scenarios. This diversity of scenarios generates complex situations of intense naval traffic, where the system must be able to track accurately not only the unitary targets, but also to fusion and targets division, including abrupt change of routes, among other characteristics that indicate situations of interest on the area under surveillance. To achieve this goal, this Project will use the tracking technique for multiple hypotheses (MHT) as an effective method to solve data association problems in monitoring systems of multiple targets (MTT). This technique forms alternative association hypotheses in case of ambiguous remark to control traces in conflict. Nevertheless, the set of hypotheses is propagated in the next processing cycles with the expectation that future observations will solve the assignment ambiguities. Thus it is expected to obtain a modem and efficient product for accurate detection of traces of multiple simultaneous OTH radar targets, including a tactical human-machine interface that allows the visualization of targets, traces and on the detection information.
