A method for filtering sea clutter in a radar echo using a hydrographic model.

摘要

A method for filtering sea clutter in a radar echo using a hydrographic model describing long waves (10) only being long waves the sum of sinusoidal components (20, 30), describing the sinusoidal components of the long waves through a dispersion relation that associates their wavenumber and frequency waves with wave direction, the sea depth, the sea current and the speed of the radar platform, which method comprises the following steps: - determination ( 1) values ​​of the hydrographic model using parameters of the radar echo; - estimation (2) of the echoes corresponding to the sea surface as deduced from the hydrographic model marine parasites; and - filtering the estimated sea clutter echo (3) of the radar.
