Micro-Doppler Features Based Parameter Estimation and Identification of Tank

摘要

摘要: 对坦克装甲车等地面活动目标进行分类与精确识别具有重要意义。微多普勒特征能反映目标的多种细微特征，在目标身份识别上具有独特优势。该文讨论了坦克目标炮塔炮管这样特有结构的微多普勒特征，基于不同种类和型号的坦克目标炮塔激励的不同微多普勒特征，提出了一种对坦克目标参数估计和精确身份识别的方法并给出一般步骤。给出了微多普勒的理论计算和仿真时频谱，仿真结果验证了理论分析与方法的正确性。为已有目标识别方法提供了重要辅助手段。

Abstract: It is important to classify and recognize ground moving targets such as armored cars. Micro-Doppler features have special advantages in identification due to the detailed information of target. The micro-Doppler features of turret and gun tube which possessed by tank only are discussed, a method or general process for parameter estimation and precise identification based on micro-Doppler features of different tank types is proposed, which can be valuable assistant technical approach to existing methods. Validity is verified with the identicalness of calculated and simulated time-frequency spectrum.
