The second step is to abstract shape signal, which uses a function to express product form information.
形态信号提取，用一个函数代表产品形态轮廓信息；

The ambiguity function of step frequency coded signal is discussed. An up-down step frequency coded signal waveform is designed with its processing method.
本文讨论了步进频率编码信号的模糊函数，提出了一种正负步进频率编码信号及其处理方法。
