Abstract
The usual spatial power spectra of ocean wave images taken from PPI of a ship radar show an ambiguity in the wave propagation direction. A simple numerical procedure is suggested and realized to remove this ambiguity. It makes use of the data from two consecutive turns of the radar antenna as well as of the wave dispersion law. The results obtained show a good agreement with the ground truth.This publication has 9 references indexed in Scilit:
