Abstract
Downlink antenna arraying is an effective method to improve the ground receiving capacity instead of the large-aperture antenna in the future deep space explorations, and that the arraying combining algorithm is the key factor in influencing the system performance. In allusion to the problem of the efficient combination under the lower SNR conditions at a Martian distance, an iterative FX correlation combining algorithm is proposed. The principle and performance of the algorithm are discussed and compared in detail, and the arraying application of the algorithm is presented in the CE mission. Simulation and experiment results intimate that adaptive FX correlation combining algorithm has a better performance than other arraying methods such as FSC and BC, and is acceptable for the arraying combining of the Martian weak received signal.
