ABSTRACT:
An arrangement is described for extracting divergence-measuring modes from a corrugated guide connected on the one hand to a corrugated horn and on the other to a utilization device. The arrangement includes at least two pairs of collector waveguides lying in diametrically opposite positions along the corrugated guide to which they are coupled by slots formed in the wall of the corrugated guide in which the divergence-measuring modes are propagated. Two, at least, of these modes are extracted as a function of their phase velocity and are processed to produce divergence-measuring signals. The arrangement is advantageously used in antennas for tracking satellites or missiles.
