| Abstract: | Antenna arraying is one of the most important development directions in deep space communication. In this paper,the evolution of antenna arraying is introduced,while key techniques are investigated in detail,including selection of array site,element diameter and quantity,array geometric configuration and signal processing algorithm. Moreover, effects of these techniques on the arraying performance are analyzed. Finally,the development trend of antenna arraying is discussed. |
