Abstract
PURPOSE: To make it possible to attain antenna tracking with high accuracy by driving an antenna unit so that the reception level of a detected pilot signal will increase and by obtaining the highest level by adjusting.
CONSTITUTION: Antenna unit 1 receives a signal wave of a single-carrier and single signal SCPC system, the signal wave receiced from unit 1 is amplified, and a pilot signal in this signal wave is extracted by pilot receiver 9. At this time, the reception level of the received pilot signal is detected by the detection circuit inside of receiver 9, antenna unit 1 is so driven that the detected reception level will increase, and antenna unit 1 is so adjusted that the highest reception level of the pilot signal will be obtained. Consquently, antenna tracking can be attained with high accuracy.
