World’s First Automatic EW Threat Classification System

Chemring Technology Solutions introduces PREFIX, a wideband electronic warfare (EW) survey system which is the first system in the world to automatically classify electronic signals to detect threats and direction find (DF) in real time.

PREFIX delivers immediate situation awareness to the dismounted operator. Integrated into Chemring Technology Solutions’ award-winning RESOLVE manpack, PREFIX enables the operator to rapidly interpret the electronic picture, prioritise signals of interest and automatically geo-locate and track on a map.

Threat pictures are developed in real time, automatically classifying signals so that threats are quickly identified, reducing the task burden for operators while allowing them to maintain tactical awareness.

PREFIX provides highly accurate DF in real time across the active 40MHz spectrum and, when networked, will provide geolocation solutions across the communications band. Even low probability of intercept signals, such as frequency hoppers and short duration signals, can be geo-located using the historic position fix data.

A single RESOLVE manpack sensor can be rapidly fitted to a vehicle with PREFIX, enabling highly accurate running-fix geolocation solutions, particularly important in high multipath environments such as complex urban areas. CESMO compatible, PREFIX can contribute and receive data from coalition partners operating in the Land, Sea and Air domains, critical for combined missions.

Gavin O’Connell, Business Sector Manager at Chemring Technology Solutions said: “PREFIX is another example of how we are focused on delivering ever more flexible EW capabilities. It offers the next step in being able to counter the next generation of threats – as opposed to simply addressing current in-theatre environments. Now integrated into the RESOLVE manpack system, PREFIX delivers complete mission flexibility for both mounted and dismounted operations.”
