Can I use Sentinel 1A and 1B together in PS-InSAR

Dear all,

I have a simple question as specified in the title. Most of the time series Sentinel SAR images that I want to use for a PS-InSAR analysis in my study area are Sentinel 1A data. But some of them are Sentinel 1B data. My question is can I use 1A and 1B data together in a PS-InSAR analysis? Is it recommended? If it is generally acceptable. Then, will it bring some potential problem?

Thank you very much!

Prats-Iraola et al. (2017) have reported high orbit accuracies for 6-day interferometric pairs of S1A and S1B: https://ieeexplore.ieee.org/abstract/document/8128258
