Narsha Experiment Panel 3 on Physics and Electronics RSG.12 on Maritime Remote Sensing

Abstract

Radar returns from sea surface roughness result from mechanisms which are comparable to those which generate sea state noise, absorb and scatter under water sound. It can be concluded that radar backscatter and acoustic quantities as ambient noise, reverberation, and transmission loss, are indeed related. The same experiment also shows that further data are needed to come to statistically more reliable relations. Due to the results obtained, it is clear that available models for the radar backscatter do not well apply under very stable near neutral atmospheric conditions and therefore lead to incorrect sea surface winds under the mentioned circumstances. Keywords: Normalized radar cross section of the sea, Acoustic propagation, Transmission loss, Reverberation, Ambient noise, Air sea interaction, Atmospheric stability, Friction velocity.
