High-Resolution Over-the-Horizon Radar Using Time Reversal
Abstract
This report describes an over-the-horizon radar with a high-resolution imaging capability using time reversal. By incorporating the extended virtual aperture concept enabled by multipath interference into a double-pass conjugate image scanning scheme, high-resolution radar imaging can be achieved without requiring extensive computation or a priori knowledge of environmental conditions. Initial proof-of-concept experimental results on several key features of time reversal, such as reciprocity, temporal focusing, spatial focusing, multipath-enabled extended virtual aperture, and polarization diversity time reversal, are demonstrated at HF or VHF.
