中文说明： 空间目标识别，采用PM算法，是路径规划的实用方法，用于信号特征提取、信号消噪，一些自适应信号处理的算法，多抽样率信号处理，构成不同频率的调制信号。
English Description：
Space target recognition using PM algorithm, is the practical path planning method for signal feature extraction and denoising, some adaptive signal processing algorithms, Multirate signal processing, constitute a different frequency modulated signal.
