Journal ArticleDOI
Direction-of-Arrival Estimation and Sensor Array Error Calibration Based on Blind Signal Separation
TL;DR: A novel DOA estimation and sensor array error calibration procedure is proposed that is independent of array phase errors and performs well against difference of SNR of signals.
Journal ArticleDOI
Extraction of Wind Direction Spreading Factor From Broad-Beam High-Frequency Surface Wave Radar Data
TL;DR: A new scheme to extract spreading factor from broad-beam HFSWR data with the MUSIC-APES algorithm that directly estimates the azimuth of positive or negative Bragg waves and their echo amplitudes and the results are very surprising.
Journal ArticleDOI

TL;DR: A new surface current inversion scheme for the HF distributed HSSWR system is proposed, which considers the unknown ionospheric state as a black box and extracts the key parameters to compute the surface current based on a scattering model.
Journal ArticleDOI
Computing Ocean Surface Currents From GOCI Ocean Color Satellite Imagery
TL;DR: This work introduces a new MCC search strategy to improve the computational efficiency of the MCC method saving 95% of the processing time and captures the evolution of the Kuroshio meander over seasonal, monthly, and weekly time scales.
Journal ArticleDOI
A New Algorithm for Surface Currents Inversion With High-Frequency Over-the-Horizon Radar
TL;DR: A current inversion model based on 2-D Fourier series expansion was developed and results indicate that the new algorithm possesses comparable accuracy for far- shore areas and better accuracy for near-shore areas when compared with the conventional method.
