L. Shemer, AN ANALYTICAL PRESENTATION OF THE MONOCHROMATIC OCEAN WAVE IMAGE BY AREGULAR OR AN INTERFEROMETRIC SYNTHETIC-APERTURE RADAR, IEEE transactions on geoscience and remote sensing, 33(4), 1995, pp. 1008-1013
An asymptotic expansion of the theoretical model for simulation of a m
onochromatic ocean wave imaging by either regular synthetic aperture r
adar (SAR), or bg along-track interferometric SAR (INSAR), and its ana
lytical approximation are considered. The model takes into account the
so-called velocity bunching imaging mechanism. The domains of validit
y of the simplified asymptotic and analytical expressions for both SAR
and INSAR imaging of the ocean waves are established by comparing tho
se solutions with the corresponding full numerical simulations. The an
alytical presentations of the SAR and the INSAR wave imaging obtained
in the present study are used to understand better the limitations and
the relative advantages of both techniques and to define the dimensio
nless parameters which govern the imaging process.
