| 摘 要： | 基于飞机旋转部件对雷达电磁波调制机理、调制参数模型以及回波特性，本文从实际对空情报雷达回波中提取了幅度、相位、周期3种调制特征，并分析讨论了3种调制特征物理意义及用于飞机分类与辨识的稳定性、有效性和局限性．在此基础上，提出了自动辨认特种军用螺旋桨飞机的文用方法一逐级最近邻特征综合分类法，并对实际回波进行了分类实验．分析与分类实验结果表明：3种调制特征具有相对不变性，对螺旋桨飞机的自动分类与辨识是有效的．

| Abstract: | Based on modulation mechanism, parameter model and return characteristics, this paper analyzes and extracts three kinds of the modulated signatures amplitude, phase and period from actual surveillance radar returns. By the analysis and discussion of stability, validity and limitation of three kinds of the modulated signatures, a hierarchical nearest-neighbor feature synthetically classifying method for propeller -driven aircrafts is proposed. The analyzed and the classified results demonstrate that three kinds of the modulated signatures are relatively unchangeable, and can be effectively used for identification of military propeller-driven aircrafts. |
