Simulation study on SAR imaging spectrum of shallow water area using Texel-Marsen-Arsloe spectrum

This paper presents the study of SAR imaging spectrum simulation using the shallow water TMA (Texel-Marsen-Arsloe) spectrum. The study area is located in Beibu Gulf of the South China Sea. The simulated study first selects coastal sea wave spectra with different water depths ranging from 10 m through 40 m to analyze the influence of water depth on SAR imaging spectrum. Furthermore, the change of SAR imaging spectrum is compared by changing the direction of waves propagation at 0°, 45° and 90°, wind speed at 10 m/s through 18 m/s and polarization modes with HH and VV at a certain water depth with an average water depth of 30m. The results discover when the water depth decreases, the SAR spectra peak moves to the high wavenumber region.
