A MIMO technique for enhanced clutter selectivity in a multiple scattering environment: Application to HF surface wave radar

The significance of multiple scattering processes whereby unwanted Doppler-spread energy can contaminate HFSWR remote sensing measurements has recently been reported. In this paper we present the results of quantitative calculations of the extent of the contamination, and then outline a solution based on the adoption of MIMO radar concepts which have been applied successfully in HF skywave radars.
