DOUBLE SIDE-BAND DOPPLER VOR EQUIPMENT.

Abstract

This report describes the design and fabrication of a Double-Sideband Doppler VOR Transmitter and Distributor. The equipment is intended to modify present Doppler VOR ground station equipment to provide the radiation of a double-sideband variable-phase signal which approximates the radio signal of the conventional VOR ground station but using the Doppler technique. The transmitting equipment consists of two sideband generators individually phase-locked to the carrier (one 9960 cps higher in frequency and the other 9960 cps lower in frequency) individual automatic level control circuits, power supplies, and associated control circuits. Testing by the contractor indicated that specifications on frequency, phase, and output level stability were met or exceeded. It was concluded that the feasibility of individual automatic phase control of side-band generators as a method of providing satisfactory r-f signals for a double-sideband Doppler VOR system has been demonstrated.
