摘　　要：本文阐述了在任意两个复信号谐波相关情况下,通过引入第三个复信号作为参考,使得在计算复信号比值时能保持时不变相位的计算方法.从理论上证明了以基波作为参考复信号能消除相位模糊的方案是行之有效的,并用简单的例子进行验证.接下来,将这种方案应用到射频大信号网络来分析非线性散射函数,在实际应用中体现了这种算法具有广阔的应用前景.We present a method for preserving time-invariant phase relationships,through introduce a third signal as a reference, when ratios are taken between two complex signals that are harmonically related. We prove that the theory taking fundamental signal as a reference to be able to eliminate the phase ambiguity is effective. After that we provide a simple example to illustrate this conclusion and show how to apply this technique when calculating nonlinear large-signal scattering function. In the practical application this algorithm manifests to have a broad application prospect.
