The invention discloses an energy aggregation degree measure-based sea and land
clutter scene segmentation method. The main objective of the invention is to solve the problem of poor segmentation quality in the prior art. According to the technical schemes of the invention, the method includes the following steps that: 1, a
radar transmitter is utilized to transmit pulse signals, a
radar receiver receives echo data, and an echo sequence in each resolution unit of the echo data is X; 2, over-M sampling
Fourier transform is performed on X, so that the frequency sequence Y of the echo sequence in each resolution can be obtained; 3, Y is utilized to calculate an energy aggregation
degree matrix E; 4, E is converted into a gray image H, and median filtering is performed on the gray image H; 5, threshold initial segmentation is performed on an image H1 which is obtained after the median filtering through utilizing an Otsu threshold segmentation method, so that an initially-segmented image B can be obtained; and 6,
morphological filtering is performed on the image B, so that a final
clutter segmentation result Z can be obtained. With the energy aggregation degree measure-based sea and land
clutter scene segmentation method of the invention adopted, the quality of sea and land clutter
scene segmentation can be improved, and real-time scene segmentation requirements can be satisfied. The method can be applied to sea and land clutter scene segmentation under a moving or static coherent
system platform.
