| 摘 要： | 针对数字式锁相环双向差动相位解调法的固定正向计数值所带来的测量误差,提出一种以NE602为核心混频芯片,用硬件电路实现的相位解调信号处理方法。该电路具有混频、滤波、放大等功能。通过实验结果分析,分辨率可提高到0.13°。

| Abstract: | Aiming at the errors of bidirectional difference phase demodulation signal process method based on DPLL,caused by its invariant forward count value,propounded a kind of phase demodulation signal process method centering on NE602,and realized the hardware circuit.Frequency mixer,filter and amplifier were all included.Accroding to the consequences,the resolution was increased to 0.13°. |
