WaveMic: Speech recognition of Chinese digit numbers from radio signals

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This paper presents a new solution to the Chinese digits speech recognition problem by reconstructing the high‐frequency harmonic and non‐harmonic components with the radio signals received by millimetre wave radar sensors. Abstract In recent years, the use of millimetre wave radio signals for speech recognition has rapidly developed.

Rotor unmanned aerial vehicle localization in the building sheltered area based on millimetre‐wave frequency‐modulated continuous wave radar

IET Radar, Sonar &Navigation, Volume 18, Issue 10, Page 1937-1951, October 2024.
A novel algorithm is proposed for localizing the rotor unmanned aerial vehicle in the common L‐shaped street building sheltered area. The proposed method is based on multipath exploitation radar. Firstly, the multipath of the drone is extracted through time‐frequency transformation, and then the drone is localized based on the position relationship ...

On the anti‐intercept features of noise radars

IET Radar, Sonar &Navigation, Volume 18, Issue 7, Page 1014-1035, July 2024.
An evaluation of the related Low Probability of Detection, of Intercept and of Exploitation is presented for Continuous‐Emission Noise Radar waveforms with different operational parameters, that is, “tailored”, and with various “degrees of randomness”. The effect of “tailoring” is analysed with prospects for future work.
