针对室内雷达目标的分类和识别问题，建立了室内钟摆目标的微动数学模型和回波模型，分析了室内钟摆运动产生的微多普勒特征。通过仿真钟摆目标的雷达回波，采用平滑伪Winger-Ville时频分析方法，提取了钟摆目标的微多普勒特征。结果表明：室内钟摆运动产生的微多普勒特征是周期为1／2钟摆周期的正弦调制。从仿真回波中提取的微多普勒特征与理论推导一致，验证了模型及理论分析的正确性。

The study is about the classification and recognition of indoor targets .The motion dynamics and echo models of the pendulum were built ,and its micro-Doppler modulation was quantitatively analyzed .And then ,the micro-Doppler modulation induced by the pendulum was extracted from the radar echo by the method of Smoothed pseudo Winger-Ville time-frequency analysis .The experimental results show that the micro Doppler features extracted from the simulation echo which is the sine modulation with 1/2 pendulum period agree well with the theoretical derivation ,which verifies that the models and the mathematical derivation are valid .
