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 differ-ence stability between multi-channel singular frequency signals.Further,a multi-channel singular-frequency phase difference stabilization algorithm was proposed to solve the greatest common divisor between frequencies and simul-taneously output frequencies to meet the requirements of phase difference stability.The testing results indicate that phase difference stabilities are less than 4° when the output frequencies are in the S-band,satisfying the requirements while effectively verifying the feasibility and flexibility of the algorithm.
