	abstract = {Previous work on Stackelberg Security Games for scheduling security resources has mostly assumed that the targets are stationary relative to the
defender and the attacker, leading to discrete game models with finite numbers of
pure strategies. This paper in contrast focuses on protecting mobile targets that
lead to a continuous set of strategies for the players. The problem is motivated
by several real-world domains including protecting ferries with escorts and protecting refugee supply lines. Our contributions include: (i) a new game model for
multiple mobile defender resources and moving targets with a discretized strategy space for the defender and a continuous strategy space for the attacker; (ii)
an efficient linear-program-based solution that uses a compact representation for
the defender{\textquoteright}s mixed strategy, while accurately modeling the attacker{\textquoteright}s continuous strategy using a novel sub-interval analysis method; (iii) a heuristic method
of equilibrium refinement for improved robustness and (iv) detailed experimental
analysis in the ferry protection domain.},
