Abstract
- In order to obtain the spatiotemporal situation of the evaporation duct accurately from a small amount of measurement data which is mixed into the noise during the transmission process affecting the high-precision reconstruction, this paper proposes an approximate message passing method (AMP) based on variable parameter threshold to realize the denoising reconstruction of noisy signals. By improving the threshold function in AMP, it is more suitable for the sparse characteristics of the evaporation duct parameters and converging more quickly. Theoretical analysis and experiments show that the overall performance of the denoising reconstruction method proposed in this paper is better than the control group.
