Range-Speed Mapping and Target-Classification Measurements of Automotive Targets using Photonic-Radar [PDF]
, 2020 The frequency-modulated continuous-wave radar is an ideal choice for autonomous vehicle and surveillance-related industries due to its ability to measure the relative target-velocity, target-range, and target-characterization.

The Vertical Ionosphere Parameters Inversion for High Frequency Surface Wave Radar
International Journal of Antennas and Propagation, 2016 High Frequency Surface Wave Radar (HFSWR), which is currently applied in over-the-horizon detection of targets and sea states remote sensing, can receive a huge mass of ionospheric echoes, making it possible for the ionospheric clutter suppression to ...

Modified Multi-Mode Target Tracker for High-Frequency Surface Wave Radar
Remote Sensing, 2018 In high-frequency surface wave radar (HFSWR), part of the radiation signal inevitably propagates upward and illuminates the target through the ionosphere due to the poor controllability of the antenna’s vertical pattern.

Knowledge-Based Generalized Side-Lobe Canceller for Ionospheric Clutter Suppression in HFSWR
Remote Sensing, 2018 High frequency surface wave radar (HFSWR) has been successfully developed for early warning and remote sensing. However, the ionospheric clutter is a difficult challenge that can make HFSWR system inefficient.
