DARPA pioneered the construction of ground-based phased array radars such as the FPS-85. This radar system had a range of several thousand miles and could detect, track, identify, and catalog Earth-orbiting objects and ballistic missiles.

Radar and communications jointly consume most of the highly desirable spectrum below 6 GHz. SSPARC seeks to develop sharing technology that enables sufficient spectrum access within this desirable range for radar and communications systems to accomplish their evolving missions.

Dec 6, 2023 · Discover the forefront of innovation as U.S. military visionaries reveal groundbreaking strides in sensor processing tailored for radar digital phased arrays of varying sizes and bandwidths.

Tracking Sparse Detections from a Phased Array Radar Abstract: The goal of our project, as part of DARPA's Beyond Linear Processing (BLiP) program, is to investigate and demonstrate the potential gain of implementing nonlin-ear and iterative …

Mar 9, 2022 · DARPA created Arrays at Commercial Timescales (ACT) with aim to shorten design cycles and in-field updates and push past the traditional barriers that lead to 10-year array development cycles, 20- to 30-year static life cycles and costly service-life extension programs.

Jan 8, 2024 · Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., have issued a solicitation (DARPA-PS-24-05) for the Scalable On Array Processing (SOAP) project.

This paper discusses the progress of this team's project known as IMPACT (Integrated Multi-use Phased Array Common Tile), which addresses a major goal of the DARPA Arrays at Commercial Timescales (ACT) program.

DARPA Arrays at Commercial Timescales (ACT) program. The goal of this program has been to develop a common technology base for Electronically Scanned Array (ESA)
