In this dissertation, the key technology of uplink array for deep space TTC is studied. Based on the concept of power combining, the theoretical analysis is made on the uplink array. The spatial power combining can be achieved in a certain power. The uplink antenna array technology is a power combiner. At first this chapter introduces the principle of power combining and leads to the concept of the uplink antenna arraying. Then analyze the theory of the uplink antenna arraying power combining, including the signal strength and antenna pattern. The influence of the number of element, spacing, phase and time delay on power combining is analyzed by simulation. At last the uplink antenna arraying power combining performance is analyzed and verified by simulation.
