ADAPTIVE ELECTRONICALLY STEERABLE ARRAY (AESA) SYSTEM FOR INTERCEPTOR RF TARGET ENGAGEMENT AND COMMUNICATIONS

摘要

An AESA system comprises a plurality of arrays, each comprising a plurality of radiating elements, each array configured for placement on a forward-facing surface of a different one of a plurality of aerodynamic control surfaces on an interceptor. A plurality of RF transmissive radome elements, each having an aerodynamic shape complementary to the aerodynamic control surface, are placed over one of the arrays. Control circuitry configures the arrays, independently or in concert, for RF target engagement and communication. Additional arrays may be positioned on side or aft-facing surfaces of the aerodynamic control surfaces for RF communication. The AESA system may be paired with an ER system for dual-mode operation.
