求翻译：在此基础上，提出了一种序贯的瞬时频率估计方法，提取了目标回波时频图中的微多普勒信号，定义了两种微多普勒特征，设计了基于微多普勒特征的角反射器干扰鉴别方法，分别采用了某导引头外场实测数据和仿真数据进行验证，表明性能良好。是什么意思？

On this basis, the instantaneous frequency of a sequential estimation method to extract the target echo time-frequency micro-Doppler signal graph defined two micro-Doppler characteristics, design based on micro-Doppler The corner reflector interference identification methods, respectively, using a s

On this basis, a sequential of the instantaneous frequency estimation methods, and extract the target echo frequency in the figure, the micro-doppler signal defines two micro-Doppler feature has been designed, based on micro-Doppler feature of the corner reflector interference identification methods

In this foundation, proposed one sequential instantaneous frequency estimate method, has withdrawn when the target echo in the frequency diagram micro Doppler signal, has defined two kind of micro Doppler characteristics, has designed based on the micro Doppler characteristic angular reflector distu
