Ferroelectric Electronic Scan Antennas

Most current radar scanning antennas utilize mechanical scanning, relying on a gimbal, motor, and gear arrangements to physically rotate/elevate the antenna. This technique is slow, gravity-sensitive, and susceptible to shock and mechanical failure. High-speed multiple target tracking cannot be effectively done by this technique. Electronic scan, however, allows significantly faster scanning, requires no mechanical/physical rotation of the antenna, and lends itself to multiple-target tracking.
