METHOD FOR FORMING OF IMAGE OF SEA VESSEL CONTOUR ACCORDING TO RADAR SURVEILLANCES Russian patent published in 2007 - IPC G01S15/89 

FIELD: control of motion of sea vessels for provision of safety of sea traffic.

SUBSTANCE: a matrix is formed that contains echo-signals from the target and from the surface sea waves, whose columns serve as radar observation rules corresponding to the angular positions of the radar antenna, a bipolar matrix of wavelet-spectra is obtained, the elements of the like polarity that don't contain wavelet spectra of the echo-signals from the sea vessel hull are excluded from the matrix of the wavelet-spectra, the value of the binomization threshold is determined, binomization of the matrix of the wavelet-spectra is accomplished, the vessel image is separated by processing of the binomized matrix of the wavelet-spectra by a morphological filter.

EFFECT: the image of the contour of the sea vessel is formed according to two-dimensional (angle-distance) radar surveillances at a complete suppression of the interference component from the disturbed sea surface.
