The invention discloses a forward-looking
radar imaging sea-surface target key point detection and recognition method. The method includes the steps that
radar echo data are quantized into a gray scale image; a
region of interest is extracted from the gray scale image, partition is performed, and a target region partition image is obtained; the
radar echo data and the
region of interest of the image are used, and a target region peak point information matrix is obtained; information merging is conducted on the target region partition image and the target region peak point information matrix, the number K of peak points in a target region in a merging result is obtained through counting, the previous K peak points are selected and serve as target effective peak points and form a target effective peak point image in a binaryzation mode, target axial features are extracted, and a target position is determined; the center of gravity of target energy is calculated and serves as the target key point. According to forward-looking radar target features, multiple mode identification methods are used comprehensively, the inherent features of a target can be reserved, meanwhile interference factors such as artifacts and side lobes can be restrained, and the recognition accuracy and the positioning precision of
radar imaging sea surface target key points are improved.
