regarding your questions, a couple of hints:
1. Sarproz by default uses a mask of sparse points based on amplitude local maxima. this helps speeding up a lot the processing, preserving anyway most of the information. also, it is adequate if you want to analyze single…[Read more]

In the modules APS Estimation, Sparse Points Processing, and Graph Analysis and Refinement, I understand that selecting “Coherence” in the “Weights” option allows SARPROZ to read the interferometric phase from the INTERFEROGRAMS folder and use the magnitude (i.e., coherence) as the weighting factor.

That said, numbers are relative and dependent also on other factors. so, it is difficult to tell you what number to use without looking at your dataset and at your results in detail. play with the numbers and observe…[Read more]

there are multiple things to consider in your case. An exhaustive answer to your question would require to discuss about various topics. You might want to take a Sarproz course to get more experience (in case, contact courses@sarproz.com). For the moment let me tell you that you should consider the APS estimation as an independent…[Read more]

at the moment, Sarproz saves the 25 reference points in a temporary variable. That variable can be accessed if you run Sarproz in Matlab using the pcodes version. You can access it if you type “fast” in the command prompt when Sarproz is running and the APS module is open and the function for automatic selection of reference points…[Read more]

regarding your first question, the outputs of the multi-channel change detection module (shortly described here https://sarproz.com/manual/rgb_module.html) are common outputs that the radar community knows how to interpret. Usually, those outputs are evaluated visually. If you want to set thresholds, you have to build them yourself, e.g. via…[Read more]
