摘要

The report describes the development and evaluation of an improved Doppler VOR System which will provide improvement of receiver compatibility with existing receiving equipment and reduction of station bearing error with some additional reduction of 'siting effects' and a reduction of counterpoise size. A new method of providing the 30 Hz amplitude modulation of the carrier, applicable to either the present Single Sideband or the Double Sideband Doppler VOR System for increased carrier power is also described.
