Overview of the Large Digital Arrays of the Space Fence Radar Space Fence, currently under construction on Kwajalein Atoll, will revolutionize Space Situational Awareness (SSA) using advanced phased array radar technology in two of the largest phased arrays to ever be constructed. Space Fence will provide catalog completeness, accuracy and timeliness with vastly improved performance in Low Earth Orbit (LEO) and capability to support missions in Geosynchronous Earth Orbit (GEO). Attaining detection and tracking performance within the large coverage volume necessitated developing advanced technologies including long-pulse high-duty factor Gallium Nitride (GaN) transmit modules, low-cost dual-polarized Radio Frequency Integrated Circuit (RFIC) receivers, and element- level digital beamforming across 86,000 receive elements. These technologies have been matured to Technology Readiness Level (TRL) 7 and Manufacturing Readiness Level (MRL) 7 based on end-to-end scaled prototypes. This paper will summarize these technologies, the design choices that led to their selection, and their application to the Space Fence phased arrays.
Joseph Haimerl, Member IEEE Mr. Haimerl has over 30 years of experience in radar design. He has been the Technical Director and Chief Architect of Lockheed Martin’s Space Fence program for the past 8 years and continues to oversee the technical aspects of the technical development, integration and deployment. Mr. Haimerl has also led the technical development of multiple other solid-state radar efforts for Lockheed Martin, and has been a significant contributor on other radar programs, like Aegis AN/SPY-1 D(V). Mr. Haimerl is qualified as a Lockheed Martin Advanced Systems Architect. Mr. Haimerl graduated with his BS in Electrical Engineering (Magna Cum Laude) from Drexel University in 1988. He graduated with a MS in Electrical Engineering from University of Maryland in 1990. At University of Maryland, Mr. Haimerl studied as a US Naval Research Lab / Systems Research Center Fellow with research interests in electronic warfare, radar target discrimination and neural networks.
