摘要
Abstract
For radar signals with time-frequency characteristics,traditional radar signal recognition methods are unable to meet the needs of accurate recognition of signal types.Therefore,it is necessary to evaluate the specific information of target radar effectively by collecting and analyzing the time-frequency characteristics in the radar signal pulse.A Convolution-Bidirectional Long Short-Term Memory(CNN-BiLSTM)hybrid neural network model is designed.The network mainly uses the time series memory characteristics of BiLSTM to deeply mine the time domain characteristics of radar signals.The weight sharing feature and the time-frequency characteristics of radar signals captured by CNN layer are combined.Then the signal characteristics of the above are used to jointly complete the identification of the radar signal modulation mode.The experimental results show that the method has high accuracy in the recognition of several radar signals,with the average value reaching 95.349%.It is better than the network using only a single feature and the traditional algorithm,and has good anti-noise ability.关键词
