Depth inversion in coastal water based on SAR image of waves

波浪数字光谱技术被建议借助于波浪的合成的孔雷达(SAR ) 图象检索沿海的水深度。基于海浪的一般分散关系，在改变水深度上的一个表面波浪的波长变化能从 SAR 被导出。接近波浪并且用海浪的一般分散关系的 SAR 图象的分析，遥感深测术的这种间接技术在福建省被用于 Xiapu 的一个沿海的区域，中国。结果证明这种技术为有可变的水深度的近岸的区域特别对沿海的水合适。

Wave-number spectrum technique is proposed to retrieve coastal water depths by means of Synthetic Aperture Radar （SAR） image of waves. Based on the general dispersion relation of ocean waves the wavelength changes of a surface wave over varying water depths can be derived from SAR. Approaching the analysis of SAR images of waves and using the general dispersion relation of ocean waves, this indirect technique of remote sensing bathymetry has been applied to a coastal region of Xiapu in Fujian Province, China. Results show that this technique is suitable for the coastal waters especially for the near-shore regions with variable water depths.
