| Abstract: | In order to improve target detection property under the clutter environment for PD radar,the problem of constant false alarm rate on APD is studied.The text emphasizes on analyzing the fundamental principles and processing methods of ML-CFAR in frequency domain,Using different methods to make a performance simulation and analysis on the distribution of classical clutter signal module.The simulation results manifest that GO-CFAR method could reach the expected effect. |
