Abstract： A new method of identifying a radar PRI modulation mode basedon CNN-BiGRU-Attention is proposed. This method combines the neural network of convolutional neural networks and bi-directional gated recurrent unit，efectively extracts the local characteristics and timing characteristics of the PRI sequence，and introduces the key pulse information in the PRI sequence to pay attention to the network recognition performance.By simulating the experiments，in the environment of pulse loss and pulse interference，this method has high recognition accuracy.

Key words：PRI modulation；gated recurrent unit neural network；mode recognition
