Abstract
The LEO constellation is a near earth polar orbit satellite constellation, which will cause a large number of beam overlap in the high latitude during the motion, and frequency multiplexing is usually used in LEO constellation to improve the efficiency of system resource use. All these factors will cause the interference between beams. The frequency interference of the whole constellation can be reduced to a large extent by closing the beam strategy of partial overlapping points, but due to the high speed movement of the satellite beams, it is still unable to guarantee the full period of the whole constellation without interference or interference below the threshold value. The dynamic adjustment strategy of the beam resource designed in this paper is based on the periodic closing strategy, using the sub-band division and frequency dynamic allocation technology, so as to better realize the global beam frequency resource allocation and interference optimization.
