Abstract EN
Due to the large number of Sigmoid activation function derivation in the traditional convolution neural network (CNN), it is difficult to solve the question of the low efficiency of extracting the feature of Synthetic Aperture Radar (SAR) images.
The Sigmoid activation function in the CNN is improved to be a rectified linear unit (ReLU) activation function, and the classifier is modified by the Extreme Learning Machine (ELM).
Finally, in this CNN model, the improved CNN works as the feature extractor and ELM performs as a recognizer.
A SAR image recognition algorithm based on the CNN-ELM algorithm is proposed by combining the CNN and the ELM algorithm.
The experiment is conducted on the Moving and Stationary Target Acquisition and Recognition (MSTAR) database which contains 10 kinds of target images.
The experiment result shows that the algorithm can realize the sparsity of the network, alleviate the overfitting problem, and speed up the convergence speed of the network.
It is worth mentioning that the running time of this experiment is very short.
Compared with other experiment on the same database, it indicates that this experiment has generated a higher recognition rate.
The accuracy of the SAR image recognition is 100%.
