FIELD: physics.
SUBSTANCE: method comprises steps of: calculating a first reference quantity which characterises a Poisson distribution assumed for characteristics that the pixels in the Synthetic Aperture Radar (SAR) image would have if the sea area were free of targets. The method further comprises steps of: selecting pixels in the Synthetic Aperture Radar (SAR) image, calculating a real quantity which characterises a real statistical distribution of characteristics of the selected pixels, and detecting a target in the sea area based on the calculated first reference and real quantities. The selected pixels are in the same sub-image of the Synthetic Aperture Radar (SAR) image, and detecting involves detecting a target in a sea sub-area of the sea area, the sea sub-area being represented by the sub-image.
EFFECT: high accuracy of target detection.
