Reflector antenna profile measurement using ultrasound
Abstract
A method for the measurement of reflector antenna surface profiles requiring no mechanical contact is described. The technique consists of placing an ultrasonic transmitter at the reflector focus and measuring the phase over the whole of the reflector aperture. Profile errors of order + or - 0.1 mm have been measured.
