Embodiment Construction
[0060] In order to better understand the technical solution of the present invention, the implementation steps of the present invention will be further described below in conjunction with the accompanying drawings.
[0061] Such as figure 1 Shown, the ship wake detection method of marine synthetic aperture radar image of the present invention comprises steps:
[0062] 1) Singular area elimination and effective data template generation.
[0063] The so-called singular area refers to the large or small extremely bright or extremely dark areas in the image, which have an extremely adverse effect on the transformation result, and need to be identified and eliminated first. These extremely bright or extremely dark areas include bright spots formed by the strong scattering of the ship itself, invalid data areas generated by the imaging device itself, or dark areas formed by ice reflection and other reasons. In this embodiment, for the general purpose of the algorithm, the local st...
