Description
The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative approaches to address challenges in the technical area of Frosty, which aims to develop technology to produce new sensing modes in the Arctic environment. The program focuses on three main topics: ionospheric spread-clutter mitigation, passive ambient-noise radar, and maritime vessel classification. The goal is to develop new approaches to provide reliable long-range detection of maritime traffic throughout the Exclusive Economic Zone. The program will explore the use of ambient indigenous noise as radar illumination and develop techniques for passive noise radar.
Key aspects of the program include:
• Ionospheric spread-clutter mitigation: Developing approaches to mitigate the effects of ionospheric clutter on radar signals.
• Passive ambient-noise radar: Exploring the use of ambient noise as a radar illumination source.
• Maritime vessel classification: Developing techniques for classifying maritime vessels using radar sensors.
The program will involve data collections and investigations into the use of ambient indigenous noise as radar illumination, with a focus on understanding the environment. The goal is to develop technology that can provide reliable long-range detection of maritime traffic throughout the Exclusive Economic Zone.
