Microwave-range imagery with an ultrawideband time reversal-based RADAR

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 [2-4] 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 physically backpropagating the focusing wave into the medium all over the frequency band and observing the expected focusing properties.
