Multi-function phased array radar (MPAR) is a conceptual radar system in the U.S. to potentially replace many mission-specific civilian radar systems with one. Regardless of the future MPAR system architecture and design choices, MPAR will have to demonstrate the ability of performing a combination of multiple tasks at the time lines comparable (or better) to current systems. In this paper we present an MPAR optimized scan strategy for performing all missions: weather surveillance, aircraft surveillance, and tracking of non-cooperative targets. The proposed scan strategy is a demonstration of the capabilities offered by modern advanced phased arrays. We provide examples of scans that meet stringent time-line requirements and ensure the simultaneous execution of multiple missions. The proposed multi-mission scan strategy utilizes Digital Phased Array capabilities to meet all mission requirements. Among these capabilities are the opportunity to use waveforms with a large time-bandwidth-product, the flexibility in transmitting multiple frequencies, and the suppleness of forming multiple beam-clusters on-receive.
