Stable Phase Difference Synthesis of Multi-Channel Singular Frequency Signals
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.
