Modulation identification and target classification are important functions for intelligent RF receivers. These functions have numerous applications in cognitive radar, software-defined radio, and efficient spectrum management. To identify both communications and radar waveforms, it is necessary to classify them by modulation type. For this, you can extract meaningful features which can be input to a classifier. While effective, this procedure can require effort and domain knowledge to yield an accurate identification. A similar challenge exists for target classification. 

In this webinar, we will demonstrate data synthesis techniques that can be used to train Deep Learning and Machine Learning networks for a range of radar and wireless communications systems including: 

  • Understanding data set trade-offs between machine learning and deep learning workflows
  • Efficient ways to work with 1D and 2D (time-frequency) signals
  • Feature extraction techniques that can be used to improve classification results
  • Application examples with Radar RCS identification, radar/comms waveform modulation ID, and Micro-Doppler signatures to help with target identification (for example, pedestrians, bicycles, aircraft with rotating blades)
  • Validation with over-the-air signals from software-defined radios (SDR) and radars.
