Abstract :
A simulation model for internal wave observation by synthetic aperture radar (SAR) has been developed based on the radar imaging mechanism of internal waves. The model consists of the Korteweg-de Vries (KdV) equation, the action balance equation and the radar backscattering model. The results of the simulation model have been used to study the image characteristics of internal waves, the optimal SAR parameters (frequency, polarization, incidence angle and look direction) for observing internal waves and the relationship between internal wave related parameters (amplitude, pycnocline depth, density variation of pycnocline) and SAR observation of internal waves
