摘　　要：从高距离分辨率观点出发，介绍了采用脉间频率步进技术来实现系统高距离分辨率的方法。阐述了脉间频率步进的高距离分辨率原理，并深入讨论了峰值功率、信噪（杂）比，采样速率以及频率稳定度等参数与系统性能之间的内在关系，为脉间频率步进系统的实现提供了理论依据。This paper,based on the view of the high range resolution,introduces the techruque of stepped-frequency pulse trains to obtain high range resolution The principle of obtaining high resolution target range profile is discussed And then we analyse some inherent correlations between such as peak power,signal-to-noise(clutter)ratio,sampling, the stability requirements of the frequency source and system perfor-mances.These are helpful for the realization of the system.
