A Hybrid CNN–LSTM Network for the Classification of Human Activities Based on Micro-Doppler Radar
IEEE Access, 2020 Many deep learning (DL) models have shown exceptional promise in radar-based human activity recognition (HAR) area. For radar-based HAR, the raw data is generally converted into a 2-D spectrogram by using short-time Fourier transform (STFT).

Doppler radar calibration system
IEEE Aerospace and Electronic Systems Magazine, 2012 The developed prototype has proved to be a useful instrument for the calibration of Doppler/range radars. The system includes innovative solutions for the generation of Doppler and distances with high precision. It is able to generate accurate Doppler shifts with a resolution higher than 4·10 -3 Hz and speeds with an accuracy of around ±2.76 ppm - from

IEEE Transactions on Geoscience and Remote Sensing, 2020 River discharge is an important variable to measure in order to predict droughts and flood occurrences. Once the cross-sectional geometry of the river is known, discharge can be inferred from water level and surface flow velocity measurements.
