Radar tasks scheduling for a multifunction phased array radar with hard time constraint and priority

This paper presents the radar tasks scheduling problem for a set of tasks called Hard Time Constraint tasks which cannot delay their processing by more than a positive constant α and for a set of tasks called Soft Time Constraint tasks which can be processed at any time. For this problem, we present a method composed of an algorithm which sequence HTC tasks; composed of an heuristic which sequence STC tasks and composed of a selection rule in order to determine which task has to be scheduled between the first task of both sequences.
