Multi-Role Electronically Scanned Array (MESA) Surveillance Radar

MESA provides the ability to dynamically adjust to each unique or emerging tactical situation. The advanced radar can extend its detection range without having to fly closer to a threat situation. By targeting its energy to the threat, the sensor can nearly double its detection range in the emphasis location, all while maintaining a full background of the entire battlespace. Compared to other surveillance radars, MESA also has higher update rates for enhanced tracking, bringing battle management to the edge of the radar surveillance envelope.

This powerful radar system enables tracking of airborne and maritime targets simultaneously, including the ability to revisit high profile targets at rapid rates.  At the same time, MESA provides a fully integrated, world-class, long-range Identification, Friend or Foe (IFF) capability to maintain continuous surveillance of the operational area.

Modern jamming threats can jeopardize the warfighters’ understanding of the environment. With MESA’s multiple channels and independent receivers, the sensor uses modern electronic protection techniques to adapt to jamming and electronic attack threats, while simultaneously maintaining situational awareness. No matter the threat, MESA ensures the warfighter retains a constant view of the battlespace.

When tracking and identifying electronic signals and targets, false alarms or thermal noise can be mistakenly identified by a surveillance radar. With MESA’s quick updates of the entire landscape, the sensor provides higher quality data – reducing inaccuracies and furthering the edge of the warfighter.

Northrop Grumman’s MESA also has a robust IFF system that recently achieved AIMS certification for a new Mode 5 for the system. Mode 5 enhances the ability to protect our warfighters by using advanced waveforms, cryptology and techniques to further the proven performance of MESA and its IFF system. An IFF system identifies if the other signal is – as the name states – friend or foe.

The state-of-the-art, combat-proven MESA sensor will soon provide the U.S. Air Force and NATO with long-range first look, first engagement advantage against even the most sophisticated adversaries. As part of an active production line, the multi-domain capabilities of MESA address global threats in the modern-day battlespace and evolving to meet future mission requirements. Australia, Turkey and South Korea have fielded the E-7 system, with production underway on the United Kingdom Royal Air Force E-7 AEW&C fleet.
