The invention discloses an underwater acoustic dataset augmentation method and system based on a conditional generative adversarial network, and the method comprises the steps: 1, obtaining the slices of a target object in a sonar dataset and a remote sensing dataset, carrying out the contour enhancement and pixel filling of a target object image in the slices, retaining the class information of the target object in the qualified slices, and carrying out the recognition of the target object; classifying and storing as samples; step 2, through a conditional generative adversarial network, augmenting the samples which do not reach a preset number threshold in the step 1; and step 3, pasting the samples reaching a preset number in the step 1 and the samples augmented in the step 2 to the seabed reverberation background image in the sonar data set, performing optimization processing on the pasted image, simulating the image into a sonar image, and forming the sonar data set. According to the method, the underwater acoustic image data set is enriched, and the development and application of the deep learning method in underwater target detection and segmentation tasks are promoted on the basis, so that the accuracy of environmental perception target detection is improved.
