Naval electronic support (ES)

The Rohde & Schwarz naval electronic support system combines radar and communications electronic support to protect national strategic and economic interests and prepare for current and future missions.

Operational environment

Naval vessels are made for naval warfare, littoral or ocean-borne combat operations. Their power projection role beyond domestic shores may include keeping sea lines of communication (SLOC) open, preventing attack by adversaries and safeguarding critical infrastructure. Missions can extend from general naval operations and exercises, coastal surveillance and patrol to search and rescue, law enforcement, resource protection and fisheries patrols, all of which require electronic support.


Naval vessels operating in littoral applications (brown-water), open-ocean applications (blue-water), or in between (green-water) are highly visible and are high value targets for adversary naval, airborne, and ground-based systems. All of these platforms pose the major threat of anti-ship cruise missiles (ASCM). The earliest possible warning of active multi-function radars, airborne interception radars and radar missile seekers is critical.

System purpose

Electronic Support (ES) is a key element of overall naval defense. Integrated into naval vessels, electronic support systems detect radar and communications emitters at maximum standoff range, identify and classify them (friend, hostile, neutral or unknown) and provide critical information for situational awareness and self-protection.

Platform protection

Defend the area of operation and protect the platform: the naval electronic support system is key for keeping threats in check and providing protection against hostile actions.

Self-protection is crucial for the survivability and battle readiness of naval vessels faced with offensive adversary measures.

The naval electronic support system detects threats early-on due to outstanding sensitivity and a range advantage, allowing more time to react. Its short reaction times are essential for initiating effective countermeasures against incoming threats.

Situational awareness

Establish and maintain control over the sea and critical infrastructure: the naval electronic support system facilitates comprehensive situational awareness and a deep understanding of the area of operation.

Comprehensive situational awareness promotes understanding of the activity of all actors in the naval area of operation that could impact security and safety.

The naval electronic support system detects and monitors radar and communications signals within its long sensor range and feeds precise, reliable data about actors into the combat management system (CMS) for decision making.


Prepare for crisis to prevent conflict: the naval electronic support system recognizes and analyzes unknown emitters and identifies new or unusual patterns.

A mission emitter database is unlikely to include every emitter the naval electronic support system receives, resulting in a negative identification.

The naval electronic support system provides enhanced technical analysis capability for on-board collection and analysis of unknown emitters, and then adds them to the database.

This enables subsequent automatic identification and supports mission success.
