Deep Learning and Time-Frequency Analysis Based Automatic Low Probability of Intercept Radar Waveform Recognition Method

International Conference on Speech Technology and Human-Computer Dialogue, 2023
As a critical component of modern electronic warfare, radar plays an essential role in target detection. Due to the characteristics of low interception, the low probability of interception (LPI) radar has better stealth; on the other hand, it challenges ...

Research on wavelength hopping low probability of intercept coherent LiDAR technology

Other Conferences, 2023
We propose a coherent light detection and ranging (LiDAR) with a low probability of intercept (LPI) based on wavelength hopping technology and phase-encoded random modulation technology to achieve long-range detection while reducing exposure risk.

Optimal Radiation Sequence Arrangement For Low Probability of Intercept

Radar, 2021
Both low probability of intercept (LPI) capacity and tracking capacity are important issues for modern radars. However, there usually exists a trade-off between these capacities. To solve the trade-off, the problem of radiation control is studied and the

Low Probability of Intercept Radar Signal Classification using Multi-Channel 1D-CNN

International Conference on Cryptography, Security and Privacy
Modern radar systems are designed to emit low probability of intercept (LPI) waveforms to avoid interception and detection by enemies. In this process, automatic radar LPI waveform recognition becomes a helpful tool for electronic counter-measures.
