Abstract

Abstract: According to the characteristics of phased array space-based TT&C satellite antenna aperture size and transponder power limitation, this paper proposes a correction algorithm based on PN code and BPSK without data modulation. At the same time, combined with multi-period coherent accumulation, the channel amplitude and phase correction accuracy is guaranteed under low signal-to-noise ratio. From the simulation test, we can see that our method has the characteristics of low interception and anti-barrage jamming.
