摘要

本文介绍了一种利用AIRSAR Cvv波段模拟岸线变化率的新方法。利用全息图算法模拟了光波的传播模式。此外，采用多普勒频率和方位截断模式模拟岸流运动和输沙量速率变化。结果表明，利用AIRSAR全息图像的相位信息可以模拟波的折射模式。岸线变化率小于-0.5m /d，表明发生侵蚀事件，精度误差为±0.05 m/d。

Holograph Interferomatery for Modelling Rate Change of Shoreline from Airsar Data

This work is introducing a new approach for modeling shoreline change rate from AIRSAR Cvv- band. The hologram algorithm has been applied to simulate the wave spectra propagation pattern. In addition, Doppler frequency and azimuth cut off models are used to model longshore current movement and rate change of sediment transport volume. The results show that the phase information of AIRSAR hologram image can be used to simulate the wave refraction pattern. Furthermore, the Shoreline change rate is less than -0.5m /day which indicates an erosion event with accuracy error of plusmn 0.05 m/day.
