Clutter Modeling from UWB Data for LPI/LPD Radarcom Signal Encoding

In this work we propose a method of clutter deconvolution and modeling using experimentally obtained UWB radar data. The obtained clutter models are then used for random sequence encoding (RSE) of radar-communication (radarcom) signals to achieve clutter-masked transmissions and improve covertness of the scheme. We present the results of clutter modeling from the laboratory data obtained with the software-defined OFDM radar system. We also present the results of communication and radar performance of the radarcom signals created using the derived clutter model. It is shown that this method has the potential to achieve secure communications in adversarial conditions, while simultaneously addressing radar sensing needs.
