Intra-pulse modulation recognition of radar signals is an important part modern electronic intelligence reconnaissance and support systems. With the increasing density signals, analysis processing multi-component have become urgent problem in current system. In this paper, intra-pulse approach for single-component dual-component proposed. First, order to adapt time-frequency energy distribution characteristics various we propose extract images (TFIs) received by Cohen class (CTFD) with...
Radar signal intra-pulse modulation recognition is an important technology in electronic warfare. A radar method based on convolutional denoising autoencoder (CDAE) and deep neural network (DCNN) proposed this paper. First, we use Cohen's time-frequency distribution to convert signals into images (TFIs). Then image preprocessing applied TFIs, including bilinear interpolation amplitude normalization. Next, design a CDAE denoise repair TFIs. Finally, Inception architecture identify the...
