DEVICE FOR MEASURING PARAMETERS OF AERIALS Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: device has array, generator which has output to be input for connecting aerial to be tested. Generator is connected with the first inputs of amplitude-phase meters; outputs of amplitude-phase meters are connected to corresponding inputs of computational unit. Control inputs of commutators are connected with output of control unit. Output of computational unit is connected to input of the control unit. Metal screen is made in form truncated pyramids which have larger bases conjugated with flat part of the screen. Axis of each pyramid crosses corresponding unit of coordinated grid of the aerial along the normal to flat part of metal screen. Array irradiator is disposed onto the smaller base of each pyramid; the irradiator is axially symmetric. Surface of metal screen is covered with absorbing material onto the side where the irradiators are located. Each irradiator is connected with the second input of amplitude-phase meter through commutator which is multichannel. Control unit has additional output for connecting aerial to be tested. EFFECT: improved precision of measurement. 5 cl, 2 dwg
