Experimental imaging of internal waves by a mm-wave radar

This paper 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 (94 GHz) has been developed at UCL. Then, two sets of experiments have been carried out above the linear flume and in the Coriolis circular wave-tank of LEGI, in Grenoble, in order to image surface wave fields in presence of an internal wave.
