Target characteristics analysis for a shipborne HF surface wave radar

open access: yesThe Journal of Engineering, 2019
In this study, based on the shipborne high-frequency (HF) surface wave radar target detection application, the first-order ocean surface cross-section for the shipborne HF surface wave radar is simulated, and the relationship between the sea clutter ...

Coverage Area Analysis of Combined Sky-Wave and Surface-Wave Monostatic High Frequency Radar

open access: yesIEEE Access, 2019
High-frequency combined sky-wave and surface-wave monostatic radar (CSSM-HF RADAR) is a new type of radar system inspired by the skywave components of high-frequency surface-wave radar (HFSWR). The new type of radar uses the combined propagation paths of

Spread Sea Clutter Suppression in HF Hybrid Sky-Surface Wave Radars Based on General Parameterized Time-Frequency Analysis

open access: yesInternational Journal of Antennas and Propagation, 2020
In high-frequency (HF) hybrid sky-surface wave radar, the first-order sea clutter broadening is severe under the action of ionospheric phase disturbance and bistatic angles. In this paper, a cascaded method is described to suppress the spread sea clutter.

A Directional Wave Spectrum Inversion Algorithm with HF Surface Wave Radar Network

open access: yesRemote Sensing
In high-frequency surface wave radar (HFSWR) systems, the retrieval of the directional wave spectrum has remained challenging, especially in the case of echoes from long ranges with a low signal-to-noise ratio (SNR).

Miniaturisation of high-frequency SURFACE wave radar transmitting antenna

open access: yesThe Journal of Engineering, 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.
