OVERVIEW: 3D air search radars in the AWACS class provide all-altitude surveillance, delivering precise range, azimuth, and elevation data for airborne targets over medium to extended ranges. These radars form the core sensor suites of airborne early warning and control (AEW&C) platforms.

GENERAL DESCRIPTION: These radar systems are designed for comprehensive airspace control and situational awareness. Mounted on airborne platforms, they scan large volumes of airspace using rotating or electronically steered arrays to deliver full 3D tracking of multiple air targets simultaneously. Unlike long-range ground-based systems, their altitude advantage allows horizon-limited detection with extended line-of-sight. AWACS-class radars are optimized for wide-area coverage, friendly aircraft coordination, and threat vectoring. Modern variants offer ECCM capabilities, IFF integration, and data-sharing with ground and naval command networks.
