Problems solved by technology

The disadvantage of this method is that only the original training data is used to train the classification model
The disadvantage of this method is that the deep learning method will inevitably fall into the local optimal solution, and the obtained model after training cannot be guaranteed to be the optimal solution, and the training results obtained by different prior settings and initialization methods are not stable.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] refer to figure 1 , the implementation steps of this example are as follows.

[0027] Step 1, generate training sample set and test sample set.

[0028] In all categories of the synthetic aperture radar SAR image set, at least 200 images of each category are arbitrarily obtained to form an initial training sample set, and all remaining samples are used to form a test sample set;

[0029] Each picture in the initial training sample set is moved up, down, left, and right by 30 pixels to obtain a 4-fold translation expansion sample;

[0030] Each picture in the initial training sample set is rotated clockwise by 45°, 90°, 135°, 180°, 225°, 270° and 315° to obtain 7 times of rotation expansion samples;

[0031] Flip each picture in the initial training sample set from left to right and top to bottom to obtain 2 times flipped expanded samples;

[0032] The initia...

Abstract

The invention discloses a synthetic aperture radar (SAR) target identification method based on a multi-parameter optimization generative adversarial network, and mainly solves the problems that the identification rate is not high during classifier training and the classifier parameters obtained by training cannot be ensured to be an optimal solution in the prior art. According to the implementation scheme, an initial training sample set and a test sample set are generated, and initial training samples are expanded to generate a final training sample set; Setting a structure and a parameter group number of the generative adversarial network; Training the generative adversarial network by adopting a multi-group network parameter cross training method, and training a discriminator in the generative adversarial network by utilizing the training set samples and the pseudo samples generated by the generator at the same time; And identifying the target model by using the trained discriminators in the plurality of groups of generative adversarial networks, adding the results obtained by the plurality of groups of discriminators, and averaging to obtain an identification result of the target model. According to the method, the accuracy of SAR target identification is improved, and the method can be used for identifying the static SAR target.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a synthetic aperture radar SAR target model identification method, which can be used to identify the model of the stationary target in the synthetic aperture radar SAR target. Background technique [0002] Synthetic aperture radar (SAR) has the characteristics of all-weather, all-time, high resolution and strong penetrating power. It has become an important means of earth observation and military reconnaissance. Automatic target recognition of synthetic aperture radar (SAR) images has attracted more and more attention. At present, most of the synthetic aperture radar SAR target recognition methods only use the original training data when training the classifier; most of the deep models used in the design of the classifier can obtain local optimal solutions. [0003] The University of Electronic Science and Technology of China proposed a SAR target recognition method b...
