摘要： Methods and Systems for testing phased antenna arrays include positioning a phased antenna array and a probe antenna at relative positions with respect to each other where one of them can operate as the transmitter and the other as the receiver. The transmitter can radiate a plurality of electromagnetic waves sequentially while the phased antenna array is steered or configured differently for each radiated electromagnetic. The receiver can receive, responsive to each radiated electromagnetic wave, a corresponding receive radio frequency (RF) signal. A processor can determine one or more performance parameters of the phased antenna array using the receive RF signals.

摘要： Systems and apparatuses include an electronically scanned array system including a power supply system, a radiating element subarray, a plurality of beamformer chips, and a plurality of control buses. The radiating element subarray includes active radiating elements, and between about one percent and about twenty percent reserve radiating elements distributed throughout the active radiating elements. Each control bus includes a plurality of primary control paths providing communication from the control bus to the beamformer chips, and a reserve control paths structured to be remapped to provide communication from the control bus to the beam former chips in the event that one of the plurality of primary control paths fails.

摘要： Systems and methods relate to an electronically scanned antenna array. A beamforming circuit includes a first input, a first output, a second input, a second output and an antenna interface. The antenna interface is coupled to the electronically scanned antenna array. A first control circuit is coupled to the first input and the first output and is configured to provide first beamforming data to the beamforming circuit via the first input. A second control circuit is coupled to the second input and the second output and is configured to provide second beamforming data to the beam forming circuit via the second input.

摘要： An antenna array testing circuit can include a circuitry including a plurality of memory registers, a testing sequence generation logic, and a testing control logic. The memory registers can store, for each antenna element of a plurality of antenna elements of the phased antenna array, a corresponding antenna element ID. The memory registers can store a testing step ID indicative of a testing step of a sequence of testing steps. The testing sequence generation logic can determine, for each antenna element of the phased antenna array, using the corresponding antenna element ID and the testing step ID, a corresponding testing signal indicative of a testing state of the antenna element during the testing step. The testing control logic can cause each antenna element the phased antenna array to be configured according to the corresponding testing signal during the testing step.
