Multiple model approaches to multisensor tracking

Abstract

This thesis has been made in the Digital and Computer Systems Laboratory at Tampere University of Technology in cooperation with the Finnish Air Force. The research is part of a larger project were tracking techniques have been studied to create more expertise of the field in Finland.In this thesis the problem of tracking airborne maoeuvering targets in clutter using angle-only measurements is considered. Three different tracking algorithms for maneuvering targets were studied, namely the Interacting Multiple Model algorithm, Interacting Acceleration Compensation and Two-stage algorithms. The algorithms were adapted for handling passive measurements from multiple sensors in cluttered environment. For the two-stage algorithm a new maneuver detector was also divised. Another problem studied was the tracking of targets having very dissimilar kinematics, using a single model bank in IMM. Two model banks capable of tracking both stationary and maneuvering targets were designed. /Kir10
