Transmitting and receiving radio frequency signals using an active electronically scanned array

摘要

A system for transmitting and receiving signals includes an array system of one or more active electronically scanned arrays. The array system includes a receive portion of a first number of receive elements and a transmit-receive portion of a second number of transmit-receive elements. A transmit-receive element includes monolithic microwave integrated circuit power amplifiers and low-loss miniature combiners. A signal processing system processes signals. A beam forming system generates receive beams of the receive elements. A receive beam has a receive beam beamwidth that is less than a transmit beam beamwidth of a transmit beam of the transmit-receive elements.
