[0002] The traditional TT&C antenna usually has only one receiving antenna to track and receive the telemetry data transmitted by the target. The traditional single antenna cannot adapt to the telemetry function of the super-high-speed target. In order to improve the target acquisition probability, many partial feed antennas are added around the main feed antenna to assist in discovering the target, so as to realize early and rapid detection, tracking and demodulation of the target signal. The partial feed beam synthesis demodulation system brings some problems to the design and development of the traditional TT&C software, especially the traditional TT&C software.

[0003] (1) Since a large amount of partial feed beam channel data is added, the software requires high efficiency in data processing capacity;

[0004] (2) Since a large number of partial feed antennas will bring some error information in the process of receiving signals, the data processing requires accuracy;

[0005] (3) Due to the number and system of partial feed antennas, the processing software needs to have good adaptability.
