Abstract :
A new formulation for ocean-depth measurement using the frequency-domain approach is proposed. Specifically, a classical high-resolution eigenstructure-based method is modified an the frequency domain to estimate the ocean depth from backscattered returns, and in this context a new technique to measure sea depth is introduced. Detailed analysis and depth determination from actual bathymetric measurements is also presented
