A novel beam model based on ultra-sparse arbitrary spatial array

In deep space exploration, the communication signal between the deep space detector and command-control center will experience a very large attenuation; the domain of this attenuation can be divided into two parts. One is caused by the spread of spherical wave; the other is due to the scattering and absorption of atmosphere and ionosphere, which value can reach to 40~50dB. If the distributed satellites communications relay can be used in deep space exploration, that the attenuation caused by the scattering and absorption of atmosphere and ionosphere can be avoided, and the quality of communication in deep space exploration will be improved significantly. This paper proposes a beam model of ultra-sparse arbitrary spatial array based on the distributed array of satellite antennas, and the simulation results confirmed the correctness and validity of this proposed model.
