The invention discloses a time reversal imaging method and system based on an ultrasonic subarray, equipment and a storage medium, and the method comprises the steps: designing a plurality of ultrasonic subarray division schemes, carrying out the time reversal imaging, defining a multi-parameter comparison function, carrying out the comparative analysis of the different ultrasonic subarray division schemes, and carrying out the time reversal imaging of the different ultrasonic subarray division schemes. And screening out an optimal ultrasonic sub-array division scheme, and outputting a corresponding ultrasonic image. Compared with an existing time reversal imaging method, only part of the array elements are adopted as the working array elements, the number of the working array elements is greatly reduced, the number of time domain signals and the data storage amount are greatly reduced, different imaging results are compared and analyzed through a multi-parameter comparison function, and the imaging accuracy
