The need for high accuracy navigation in deep space exploration has triggered the development of interferometry technology in deep space TT&C. This paper describes the design and implementation of a new DBBC sub-system of the deep space interferometry digital backend. The DBBC sub-system can process two IF analog signals with 512MHz bandwidth and output at most 16 channel baseband signals with...
In this paper, analysis and simulations are presented to show that using array antennas in deep space communication can increase the signal collecting aperture and enable beam forming, array received signal model is build, and multiple signal classification (MUSIC) algorithm introduced to increase suppression of interference is implemented on a simulated array system. Simulation demonstrates that...
