1. An ultrasound beamforming method for suppressing clutter, wherein the method comprises:
obtaining channel data of ultrasound echo signals;
applying a conventional apodization function to the channel data of the ultrasound echo signals to obtain a signal dataset, and applying a random apodization function to the channel data of the ultrasound echo signals to obtain a noise dataset, wherein the random apodization function is obtained by orthogonalization of the conventional apodization function;
calculating correlation coefficients of the signal dataset and the noise dataset in two directions within a coordinate system;
calculating processed spatial data for each point in the ultrasound echo signal channel data based on the correlation coefficients and the signal dataset;
forming the ultrasound beam based on the processed spatial data to generate imaging data.
