[0025] The HRRP target recognition method based on deep learning is a simple and effective solution. Aiming at the problem that the HRRP target recognition method based on deep learning is vulnerable to attack by adversarial samples, the present invention proposes a method for generating targeted attack adversarial samples for HRRP. Among them, the perturbation of a single sample is generated by the method of multiple iterations, and the general perturbation is generated by the method of scaling. Some basic concepts related to the present invention are:
[0026] 1. Deep neural network: Deep neural network refers to a multi-layer neural network, which is a technology in the field of machine learning. Its characteristic is that the input of the hidden layer node is the output of the upper layer network plus the bias, and each hidden layer node calculates its weighted input mean, and the output of the hidden layer node is the result of the nonlinear activation function. At the s...
