Title:
TRACKING DEVICE AND METHOD FOR ADJUSTING PHASE
Document Type and Number:
Japanese Patent JP2009175037
Kind Code:
A
Abstract:

To provide a tracking device capable of performing optimum adjusting of a phase even while a movable body is moving.

A tracking reception section extracts signals of an orthogonal component generated corresponding to a deviation between a direction of a radio source and a main axis direction of an antenna for tracking the radio source from an output of the antenna. A phase adjusting section superposes an AC signal to one of the signals of the orthogonal component and adjusts the phase of the signals of the orthogonal component so as to suppress an interference component occurring on the other signal of the orthogonal component.
