The invention provides a plane wave beam forming method based on deep learning. The plane wave beam forming method comprises the following steps of matrix sample acquisition, model training, precisiondetermination and beam forming. The invention further relates to a plane wave beam forming system based on deep learning, a storage medium and electronic equipment. The invention discloses the planewave beam forming method based on deep learning. The method obtains a first matrix sample and a second matrix sample by emitting ultrasonic imaging beams to to-be-detected tissues at the same positionthrough a matrix ultrasonic imaging probe, and trains a network by taking a plurality of groups of first matrix samples and second matrix samples which are obtained at different positions and are inone-to-one correspondence as an input end and a marking end respectively to obtain a beam forming model; and through the beam forming model, the imaging quality of a high-angle-number transmitting sequence can be obtained through a low-angle-number transmitting sequence, so that a high-frame-frequency and high-resolution image is obtained.
