Holographic imaging by satellite radars is precisely analyzed on a wave propagation theory in turbulent media. The variance of reconstructed images is expressed in an analytic form for strip objects. The turbulence effects on the image resolution are made clear numerically.

This paper presents methods for estimating the ocean wavelength in satellite altimetry and discusses the possibility of detecting the ocean wavelength. Numerical analyses show that there exists a relation between the significant wavelength and the pulse-to-pulse correlation coefficient. Presented methods are based on processing the data of existing satellite altimeters. Accordingly, we will be able to propose a method for measuring the wavelength without a large change in existing altimetry system.
