THE DETERMINATION OF NEARSHORE WAVES PARAMETERS BY THE INTERFEROMETRIC SYNTHETIC APERTURE RADAR

Abstract

Nearshore zones have a significant impact on life and economics. Along with the weather and climate stabilizing factor, caused by the water proximity, on the border of land and sea occur specific gradients and flows of heat, moist, pressure, etc. They might cause dangerous nature phenomena such as hurricanes, floods, etc. which need to be predicted and monitored. The remote sensing of neashore zone might be a part of such monitoring. The results of microwave remote sensing of neashore zone of New River inlet obtained by frequency-modulated continuous wave along-track interferometric synthetic aperture radar are presented. The estimation of neashore waves parameters such as wave height, phase velocity, etc. using ATI SAR images are performed. The algorithm for the estimation of bandwidth and shape of the radial velocity spectrum of braking wave is proposed and the dependence of the bandwidth of radial velocity spectrum on significant wave height is obtained.
