调频步进信号是一种新的高距离分辨率信号。文章首先简要阐述了线性调频信号的处理过程；其次对比步进频率、线性调频步进信号的处理过程，得到一种新的处理方法-合成处理法，最后通过仿真论证其正确性。

The frequency modulate by a stepped frequency is a novel radar signal with high range resolution. In this paper, the process of frequency modulate is expounded first. By contrasting the process of the stepped frequency and linear frequency modulate signal, it can get the new process method of the frequency modulate signal. In the end demonstrate its correctness in simulation.
