The Study on Wide Area Antenna Array Algorithm and Its Experiments

Zhu Xinying; Kong Deqing

In wide area antenna array, it is difficult to combine the signal of each element because of the big delay and phase offset. Prior values of delay and delay rate, calculated according to the position and velocity of space probe and ground antennas, are used for correlation of antenna signal. The signals from each array element could be combined using residual delay, delay rate and phase offset obtained by correlation .Observation data received by Shanghai Sheshan 25-meter-diameter antenna and Beijing Miyun 50-meter-diameter antenna during Chang’E-2 lunar satellite mission are processed to verify the above algorithm. The experiment result indicates that the signals from each antenna could be combined successfully.
