Abstract :
The tracking error of a phased array antenna between transmitting and receiving frequencies was measured by in-flight experiments using a geostationary satellite. The tracking error was found to depend on beam-scanning angle and the ratio of transmitting and receiving frequencies. Measured results agreed well with a theoretical prediction. An effective method to eliminate the tracking error is proposed
