Time Reversed Over-The-Horizon Radar
Time reversal can play a significant role in improving the performance of current sky-wave high-frequency over-the-horizon-radar (HF OTHR), especially with respect to real-time monitoring and compensation of ionospheric turbulence. Also, multipath interference arising from an HF OTHR environment can significantly increase resolution and the signal-to-clutter-ratio. Furthermore, the proposed double-pass time-reversal EVA method incorporated into active beam steering has the potential to provide high-resolution radar imaging. Currently, a test site is being built between the Chesapeake Bay Detachment (CBD) and Tilghman Island in Maryland to prove the concepts of the proposed system.
