Multi-function phased array radars (MFPARs) are capable of executing several tasks without any rotating antenna by jointly optimizing limited time and energy resources. The allocation of radar time resources is usually referred to as scheduling in radar resource management (RRM) literature. In this thesis, two scheduling algorithms, namely multi-type adaptive time-balance scheduler (MTATBS) and knapsack scheduler (KS), are proposed for real-time operations. A resource-aided technique called as the multi-frequency band usage is developed to increase the applicability of task interleaving. A simulator for MFPAR system is implemented to apply RRM techniques with different optional choices, such as adaptive update-rate, dynamic task prioritization, tracking, task interleaving. The simulator is designed in a way that each of the blocks can be individually modified according to RRM constraints. Target selection problem emerges when there are more than one target concurrently requesting track update. It is suggested to adopt the solution methods for the well-known machine replacement problem to the problem of target selection and track update is solved with the method of decision policy (DecP). In addition to this method, two other ad hoc methods based on track quality are described.
