AUTOMATIC SYSTEM FOR RECORDING THE AMPLITUDE AND PHASE CHARACTERISTICS OF DIAGRAMS OF ANTENNA DIRECTIONALITY,
Abstract
The object of the invention is an automatic device for recording the amplitude and phase characteristics of directionality diagrams of antennas designed in accordance with the system of different channels of measurable and reference signals. Simultaneous measurement of amplitudes and phases of the currents of UFH with high precision is assured by the use of slave motors and an attenuator connected with them of the limiting type with little initial attenuation. A broad-band UHF phase converter is used for the automatic maintaining on the input of the receiver of a constant amplitude of the measurable UHF signal and difference of phase between the reference and the measurable UHF signals. A servo system is used for measuring the independent coordinate and the displacement of the tape. The tape simultaneously records the amplitude and phase diagrams of the directionality of the antennas.
