Patria has officially unveiled its next-generation Electronic Support Measures (ESM) surveillance system, Patria CATCHR, at the EW Live 2025 exhibition in Estonia. Designed to operate in today’s increasingly complex electromagnetic environment, the system delivers real-time situational awareness while remaining fully passive and undetectable to adversaries.
“In today’s crowded electromagnetic battlespace, even the faintest signal can reveal a critical threat. Staying ahead requires early and accurate detection, supported by covert and agile passive sensors to ensure mission survivability. We are proud to launch Patria CATCHR as an innovative solution in this field,” said Mikko Leino, Executive Vice President of Patria’s Defence and Weapon Systems business area.
Superior Intelligence in Electromagnetic Battlespace
The Patria CATCHR combines the full capabilities of a high-performance ESM system with advanced signal intelligence functions. It intercepts, geolocates, and tracks radar emissions, building a recognized situational picture and enabling operators to analyze complex signal patterns.
When deployed as a distributed sensor network, the system provides passive wide-area coverage, remaining invisible to enemy detection and offering commanders the ability to launch rapid, informed countermeasures against evolving threats.
Advanced Capabilities
-
Passive Operation: Detects without revealing its own position, ensuring survivability.
-
Signal Detection: Identifies and classifies even the weakest radar emissions in dense electromagnetic traffic.
-
High Precision Geolocation: Accurately tracks threats across contested environments.
-
Scalable Networked Deployment: Enhances coverage and resilience when linked as a sensor network.
Built on advanced signal processing algorithms, Patria CATCHR is engineered to perform under operational pressure and provide superior intelligence advantage in both national defense and allied missions.
Strengthening Situational Awareness
Patria’s unveiling of CATCHR at EW Live 2025 in Tartu underscores its commitment to advancing next-generation surveillance solutions for the global defense market. By combining cutting-edge signal intelligence with stealthy passive operations, the system enhances mission survivability and ensures decisive situational awareness in the electromagnetic domain.
