Abstract：For the reception of shortwave skywave signals,a signal enhancement technology is proposed in this paper.A large aperture vector antenna array is used in the front end to improve the multi domain information interception and perception ability of shortwave signals.In the back end,polarization spatiotemporal array processing is used to finely separate and synthesize shortwave multipath signals,and multi-dimensional equalization based on neural networks is used.Compared with traditional scalar array syn-thesis methods,the signal-to-noise ratio is improved.The signal demodulation has better performance in terms of error rate and oth-er aspects,which can effectively improve the anti fading reception ability of shortwave signals.
