Hi, I have a question about the phase misalignment between the two rx port.
In my application, i use one tx port and two rx ports to measure the distance, the structure of the system can be seen in the affliated file. the tx lo and the rx lo has a constant IF, in my application, 5MHz ,I assume that the only phase difference between the IF from rx1 and rx2 come from the different paths between the tx and rx ports. But the results shows there are many more. i have been dealing with this for a really long time, yet, nothing come to my mind. Any help would be appreciated. Thanks in advance.
