Patria CATCHR Introduced at EW Live in Tartu

Patria showcases its new high-performance ESM (Electronic Support Measures) surveillance system Patria CATCHR at the EW Live exhibition in Tartu on September 23, 2025. The system delivers real-time situational awareness by cutting through the noise — enabling fast, informed actions and precision countermeasures.

“In today’s crowded electromagnetic battlespace, even the faintest signal can reveal a critical threat. Staying ahead in intelligence and surveillance requires early, accurate detection and the ability to distinguish targets from a dense and dynamic signal environment. Vulnerable active sensors must be complemented with covert and agile passive sensors to ensure mission survivability. We are proud to launch this new innovative product in this area, Patria CATCHR,” says Mikko Leino, Executive Vice President of Patria’s Defence and Weapon Systems business area.

Patria CATCHR delivers the full capabilities of a high-performance ESM system combined with advanced signal intelligence features. It intercepts, geolocates, and tracks radar emitters generating a recognized situational picture, while allowing operators to explore detailed signal patterns. When deployed as a distributed sensor network, the system provides passive, wide-area surveillance that remains invisible to adversaries - offering superior situational awareness and enabling rapid countermeasures against evolving threats.

Patria CATCHR is designed to perform under pressure. Built on advanced signal processing algorithms, it sorts through dense electromagnetic traffic, detects and classifies even the weakest radar emissions, geolocates threats with high precision, and operates completely passively, without revealing its own position.
