| 摘 要： | 为了解决多通道奇异频率间相位差稳定的难题,理论上分析了锁相环稳相原理,提出了一种多通道奇异频率的稳相算法。该算法通过求解奇异频率间的最大公约数,联动输出频率的同时可满足稳相合成的条件。电路实物加入适当的环路阶型设计,当输出频率在S波段时,相位差稳定性≤4°,满足使用需求,同时很好地验证了该算法的可行性和灵活性。

| Abstract: | The PLL phase stabilization principle was theoretically analyzed to solve the problem of phase differencestability between multi-channel singular frequency signals. Further, a multi-channel singular-frequency phasedifference stabilization algorithm was proposed to solve the greatest common divisor between frequencies and simultaneouslyoutput frequencies to meet the requirements of phase difference stability.The testing results indicate thatphase difference stabilities are less than 4° when the output frequencies are in the S-band,satisfying the requirementswhile effectively verifying the feasibility and flexibility of the algorithm. |
