| Abstract: | Many ship target detection methods have been developed since it was verified that ship could be imaged with the space-based SAR systems. Most developed detection methods mostly emphasized ship detection rate but not computation time. By making use of the advantages of the K-distribution CFAR method and two-parameter CFAR method,a new CFAR ship target detection algorithm was proposed. In that new method,we use the K-distribution CFAR method to calculate a global threshold with a certain false-alarm rate. The... |
