中文摘要：
为提高高频地波雷达的抗干扰能力，提出了一种在线性调频中断连续波的基础上基于跳频技术的新高频地波雷达体制，并从整体上对这一新体制进行了阐述，在分析了这一新体制优缺点的基础上，对由跳频引起的旁瓣过高这一缺点，采用三次样条插值方法实现对不可靠数据的替代来进行弥补，最后给出了这一体制雷达的理论分析和系统仿真结果。
英文摘要：
The paper presents a new radar system based on Frequency Modulated Interrupting Continuous Wave （FMICW） by exploiting the hopping frequency technique to improve the capability of HFGWR. An introduction is given to the whole structure of the hopping frequency. Then an analysis is made of the advantages and disadvantages of the radar, and a new method is proposed on the basis of cubic spline function which can overcome the disadvantage of high sidelode caused by hopping frequency. Theory analysis and simulation results show that the sidelobe can be suppressed with the method of interpolation.
