摘要：
The application of the Doppler Beam Sharpening (DBS) technique is shown for a free moving maritime target using a 150 GHz FMCW radar equipped with 10 degrees horn antenna. The methodology of synchronizing the radar data with the spatial and inertial data is presented with the resulting DBS imagery from the scene at Coniston Water, UK. DBS with sub-THz (above 0.1 THz) radar was found to be an effective tool for producing images with range resolutions on the order of cm and azimuth resolutions of near 0.1 degrees. This resolution was found to be more than 100 times more refined than the 150 GHz horn antenna azimuth beamwidth.
