Motion compensation for platform-mounted high frequency surface wave radar

Abstract

A method for mitigating antenna motion effects in high frequency radar Doppler spectra developed from ocean backscatter is proposed. Based on the established radar cross section models for a fixed antenna and for an antenna on a floating platform, the relationship between these models is developed. Through this relationship, motion compensation can be achieved by deconvolving the radar cross section data with the derived transfer function. A least squares deconvolution (LSD) method is applied in this study and shows good performance.
