Abstract

A radar wave original data enhancement method based on a metamorphic method comprises a data metamorphic module and a data imaging module. The data metamorphic module analyzes a radar signal transmitting and receiving method, a radar wave original data storage rule and a set of effective radar wave data enhanced metamorphic method, and finally multiple sets of marked radar wave data are obtained. The data imaging module takes SAR radar wave original data as an experiment object, is responsible for imaging marked SAR radar wave enhanced data, and enables synthesized images to be in one-to-one correspondence with the marked radar wave data.

Description

technical field [0001] The invention belongs to the field of data enhancement, in particular to radar wave data enhancement. After understanding the generation principle of radar wave raw data, a set of metamorphic relations that can be enhanced is obtained according to the radar wave data information collection rules. Background technique [0002] In recent years, deep learning has been developing continuously, and various models generated by deep learning have been widely used in our lives. In the era of deep learning, the larger the scale and the higher the quality of data, the better the generalization ability of the model, and the data directly determines the upper limit of model learning. However, in actual engineering, it is difficult for the collected data to cover all the scenarios. In order to enrich the training set, data enhancement is generally performed on the data. On the one hand, the significance of data enhancement is to improve the generalization ability...
