IN-FIELD MILLIMETER-WAVE PHASED ARRAY RADIATION PATTERN ESTIMATION AND VALIDATION

Abstract:

An apparatus for calibrating a multi-antenna system includes an unmanned aerial vehicle (UAV). The UAV includes one or more millimeter-wave (mm-wave) single channel radios that can transmit and receive a mm-wave signal to or from a multi-antenna system under test; at least one directional antenna connected to the one or more radios; sensors that determine a position of the UAV; an omni-directional mobile or Wi-Fi transceiver that communicates with an operator; and a digital microprocessor unit connected to the one or more mm-wave single channel radios, the sensors, and the omni-directional mobile or Wi-Fi transceiver. The digital microprocessor unit can control motion of the UAV and analyze signals received from the one or more min-wave single channel radios and the at least one directional antenna using position information received from the sensors.
