摘　　要：在传统的延迟锁相环路的基础上提出一种工程上易于实现的线性调频连续波线性度校正的方法,对其校正原理作了详细描述,并对这种校正方法进行计算机仿真分析。从仿真和实际应用的结果可以看出,该方法提高了线性调频连续波雷达扫频源的线性度,满足了其高精度测距的实际需要。This paper proposes a new linearity correcting method of LFMCF, which can be easily realized in engineering based on traditional delay PLL. The correcting principle is described in detail. And the computer simulation of this method is performed. The results show that the linearity of the frequency-swept generator is raised, and the practical requirements of high distance resolution of LFMCW radar can be satisfied.
