基于频域CFAR方法的PD雷达回波信号处理

摘要

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.%为了提高PD雷达杂波环境下的目标检测性能,研究了机载PD雷达恒虚警检测问题.重点分析了频域均值恒虚警处理的基本原理与处理方法,采用不同方法对雷达面临的典型杂波分布信号模型进行了性能仿真分析.仿真结果表明,最大选择恒虚警处理方法能够达到预期效果.
