Vibrometry and Sound Reproduction of Acoustic Sources on Moving Platforms Using Millimeter Wave Pulse-Doppler Radar [PDF]

open access: goldIEEE Access, 2020
This paper presents millimeter wave (MMW) pulse-Doppler radar for the remote sensing of acoustic vibration for targets in motion. A key advance in this work is the development of precision motion compensation for MMW vibrometry, making it possible for a ...

Improved spectral processing for a multi-mode pulse compression Ka–Ku-band cloud radar system [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
Cloud radars are widely used in observing clouds and precipitation. However, the raw data products of cloud radars are usually affected by multiple factors, which may lead to misinterpretation of cloud and precipitation processes.

OTFS Based SAR With Low Complexity Receiver

open access: yesIEEE Access, 2023
Synthetic aperture radar (SAR) are exploiting millimeter-wave (mmWave) band for imaging applications. However, with the conventional pulse-width of few tens of microseconds the receive SAR signal experiences intra-pulse Doppler shift in mmWave band which

Reduced time-on-target in pulse Doppler radar: Slow time domain compressed sensing [PDF]

open access: greenInternational Radar Conference, 2016
Pulse Doppler radars measure both the targets distance to the transceiver and their radial velocity, through estimation of time delays and Doppler frequencies, respectively.
