Abstract

Polarized sensor is able to investigate the coastal problems such as erosion and sedimentation. AIRSAR polarized sensor could be an ideal concept in developing such sensor. In this context, this work is introducing a new approach for modeling the rate of shoreline deformation from AIRSAR C_vv band. The hologram algorithm has been applied to simulate the wave spectra propagation pattern. The results show that the phase information of AIRSAR hologram image can be used to simulate the wave refraction pattern. Thus, the rate of shoreline deformation is  ranged between -0.005 to 1.0 m with bias of -0.06 m and standard error of  ± 0.042 m. In conclusion, there is an excellent promise which is introduced by holograhic interferometry to model the deformation of shoreline.
