# DARPA Selects Teams for THz Radar Development

DARPA selected Riverside Research and Oklahoma State University through its Expedited Research Implementation Series (ERIS) Marketplace to develop a terahertz radar sensor designed to detect and track objects smaller than an inch. The effort emphasizes fieldable size, weight, and power constraints, positioning it as a defense R&D opportunity for organizations with relevant radar, sensing, and compact-system development capabilities. No contract value, award date, solicitation number, or contact information was reported.

- The selection identifies Riverside Research and Oklahoma State University as the development team; researchers and program staff named in the signal include Rajind Mendis, John O’Hara, and Josh Wetherington.
- Companies with relevant sensing and radar capabilities can use DARPA and ERIS channels to identify follow-on opportunities, as noted in the signal.
- The focus on fieldable size, weight, and power constraints highlights operational integration as a central consideration for prospective contributors.
