An s-band ultrawideband time reversal-based RADAR for imaging in cluttered media

This work presents a new RADAR prototype built for the purpose of imaging targets located in a cluttered environment. The system is capable of performing Phase Conjugation experiments in the ultrawideband GHz. In addition, applying the D.O.R.T. method to the inter-element matrix allows us to selectively focus onto targets, hence reducing the clutter contribution. The system has been validated by ph-syically backpropagating the focusing wave into the medium all over the frequency band and observing the expected focusing properties.
