摘　　要：根据频率测量中的主要误差来源,提出利用最佳分频来实现高精度频率测量的方法。针对导弹测量的实际应用,以计数测频法中的等精度测频法为基础,利用最佳分频的2条原则,在QUARTUS平台上对设计进行仿真。仿真结果证明:该方法能继承等精度测频的优点,满足100 MHz以内的频率测量,改进等精度测频需要固定的闸门选通时间的不足。In order to solving the errors of frequency measurement, and put forward the method of best frequency-divider to realize high-accuracy frequency measurement. It aimed at the problems of missile measurement, in the end the design was simulated on the QUARTUS platform by the two principles of best frequency-dividing method based on equal-accuracy frequency measurement. Finally it was proved that the best frequency-dividing method inherited the advantages of equal-accuracy frequency measurement, it was able to measure frequency within 100 MHz, and it also bettered the disadvantages of equal-accuracy frequency measurement whose open time of counter is fixed.
