Experimental imaging of internal waves by a mm-wave radar

Describes experimental work performed within the Mesoscale Ocean Radar Signature Experiments (MORSE) project as part of the EC MAST-III programme. The aim of these experiments is to further the understanding of the imaging of internal waves by satellite SAR. Of particular interest to the project is the dependency of the imaging process on the radar wavelength in the millimetre range. Hence a laboratory mm-wave FMCW SAR (91 GHz) has been developed at University College London. Then, two sets of experiments have been carried out above the linear flume and in the Coriolis circular wave-tank of Laboratoire des Ecoulements Ge/spl acute/ophysiques et Industriels in Grenoble, in order to image surface wave fields in the presence of an internal wave.
