An Array Calibration Method Using Spatial Correlation Properties for HFSWR
This paper focuses on calibration of uniform linear array (ULA) for high frequency surface wave radar. A novel algorithm is proposed based on spatial correlation properties of the calibration source. We can estimate amplitude from the main diagonal elements of spatial correlation matrix, and obtain DOA (direction of arrival) estimate of the calibration source by two-dimension FFT. The spatial correlation matrix could be estimated in temporal domain and frequency domain, which performs better in low SNR case. It is shown through Monte Carlo simulations and experimental results that this method is practical and reliable.
