Finnish defence firm Patria has signed a contract to deliver its MUSCL passive radar system to an undisclosed European NATO member state, the company confirmed in a recent press statement.
The deal covers multiple sensor stations needed to cover a large area of interest, along with spare parts, support and training services. These elements are designed to enable rapid operational deployment for the customer.
Patria brings more than three decades of experience developing passive radio frequency sensor systems for intelligence, surveillance and electronic countermeasures. The contract reinforces its standing as a leading supplier of next-generation surveillance and situational awareness technology for modern militaries.
Mikko Leino, Executive Vice President of Patria’s Defence and Weapon Systems business area, commented that the agreement reflects strong customer confidence in the company’s passive sensor technology. He added that demand for passive radar is rising across Europe as forces strengthen air defence and counter-unmanned aircraft system (C-UAS) capabilities without revealing their own positions.
MUSCL is a transportable passive radar system that detects, tracks and reports aerial targets in real time. It exploits existing transmissions in the surrounding electromagnetic environment, giving operators enhanced situational awareness for air surveillance, early warning and C-UAS missions.
Patria will showcase the technology at the Electronic Warfare Live (EWLive) event in Estonia, running from 15 to 17 September 2026. There, the MUSCL system will operate alongside Patria’s CATCHR electronic support measures (ESM) system, delivering real-time airspace awareness over Estonia and southern Finland without transmitting any signals of their own.
The contract underscores a broader European push toward passive detection technologies, as militaries seek covert, cost-effective alternatives to traditional active radar systems.
