Abstract
A feeding method and device, particularly for a Doppler VOR system, and to a Doppler VOR system using such a feeding device. The feeding method performs a blending function, which is an approximation of the sinX/X function limitedly to the three central lobes, and is obtained by amplitude overmodulation of a single signal according to a periodic function. The blending function can be controlled through the control of the periodic function.
