如果我没记错的话,VNA(Keysight,Anritsu,R& S)通常会进行ICZT(反向啁啾Z变换)。
它与IFFT类似,更多的是分拆,有助于您的delta t分辨率。
这肯定比使用矩形窗口做标准IFFT更复杂,以防你想知道。
是德科技在这个问题上有一些非常好的白皮书。

If I recall correctly, VNAs (Keysight, Anritsu, R&S) typically do a ICZT (Inverse Chirp Z-Transformation). It's similar to IFFT and more of a spin off and helps with your delta t resolution. It's definitely more complex than doing a standard IFFT with a rectangular window, in case you're wondering. Keysight has some pretty good white papers on this subject.
