Tracking of a single ground target using GMTI radar detections is considered. A Variable Structure-
Autonomous- Interactive Multiple Model (VS-A-IMM) structure is developed to address challenges
of ground target tracking, while maintaining an acceptable level computational complexity at the same
time. The following approach is used in this thesis: Use simple tracker structures / incorporate a priori
information such as topographic constraints, road maps as much as possible / use enhanced gating
techniques to minimize the eect of clutter / develop methods against stop-move motion and hide
motion of the target / tackle on-road/o-road transitions and junction crossings / establish measures
against non-detections caused by environment. The tracker structure is derived using a composite
state estimation set-up that incorporate multi models and MAP and MMSE estimations. The root
mean square position and velocity error performances of the VS-A-IMM algorithm are compared
with respect to the baseline IMM and the VS-IMM methods found in the literature. It is observed
that the newly developed VS-A-IMM algorithm performs better than the baseline methods in realistic
conditions such as on-road/o-road transitions, tunnels, stops, junction crossings, non-detections.
