Miniaturisation of high‐frequency SURFACE wave radar transmitting antenna
The Journal of Engineering, Volume 2019, Issue 19, Page 6222-6225, October 2019., 2019 Antennas operating in the high‐frequency (HF) bands are generally relatively large in size, which severely limits the application of the antennas. Therefore, miniaturisation of the antenna is necessary. Here, a dual‐folded structure Yagi antenna is designed for HF surface wave radar (SWR).

Target Detection in Clutter/Interference Regions Based on Deep Feature Fusion for HFSWR
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 High-frequency surface wave radar (HFSWR) is of great significance for maritime detection, but in the HFSWR echo signal, ship targets are often submerged in a variety of clutter and interference, making it difficult to detect vessels.
