Full waveform inversion (FWI) can yield high resolution images and has been applied in Ground Penetrating Radar (GPR) for around 20 years. However. appropriate selection of the initial models is important in FWI because such an inversion is highly nonlinear. The conventional way to obtain the initial models for GPR FWI is ray-based tomogram inversion which suffers from several inheren... https://www.jmannino.com/limited-find-We-The-People-Flag-Unisex-Poly-Rich-Blend-Tee-great-choice/
