摘　　要：该文分析了连续波雷达参差多频测距算法的局限性,提出了多频连续波雷达的两种测距算法,即多频到双频测距法和二次相差法,并介绍了它们的基本原理。最后对两种方法进行了对比,并进行了仿真。仿真结果表明, 两种测距算法都达到了比较高的测距精度,在最后双频对应的最大不模糊距离相同的基础上,两种算法的测距精度相当。This paper analyses the limitation of the algorithm of stagger multiple frequency for CW radar, and two algorithms are proposed.They are the algorithm of multiple frequency to dual frequency and the algorithm of quadratic phase difference.Their principles are introduced. Finally, two algotithm are compared with each other, simulation result is also given.The simulation result shows that two algorithms both reach high ranging accuracy. They have equivalent ranging accuracy if their maximal unambiguous ranges of the last dual frequency are the same.
