In-game description:
"Early warning radar provides information on incoming attacks. Higher levels give more accurate information.
Early warning radar provides not only an early warning of impending attacks, but will probe the enemy fleet and conduct rapid feedback. The higher the level of the radar, the wider the range, and the more accurate the probed information."
