摘要：Step-Frequency signal is widely used in radar systems. However it suffers from the technique challenges that are the imaging moving-targets. In this paper, a new compound modulation signal is analyzed. It combines phased code modulation during the pulse and Step-Frequency modulation between the pulses time, and it is called as phase-coded Step- Frequency signal. Numeric simulation comparison experiments show that PCSF signal can get the same imaging result with less pulse number, which can be used to solve the conflict problem, such as the number of pulse and transmit average power. So this compound modulation signal can be widely used in the application of engineering project. Finally, the processing method of PCSF is simple analyzed, and numerical simulation proves its effectiveness and accuracy.
