Did anyone know about the Radar Cross Section Threshold? What is the typical value for reasonable PSC? I am using TSX 3 meter SM data

Thanks for your suggestion. I am trying, ‘Height’ here mean the accumulative height, doesn’t it?

The result estimated by linear trend is not so impressive. I shall consider use the smart5, but how to make it export the geocoded SPP displayed on the Googleearth? Last time I directly use the smart5, system give an error on the miss of inupt Vel.mat.
The result does not show the main subsidence in Xiaodian area, which was eager to detected.

I think I made a mistake, it was the logical cores…

I change to a 8 core machine, why the SARproz can only find 4 local workers?

stevexu started the topic Generic question about PS preliminary selection in the forum Sarproz Forum 9 years, 1 month ago
I do got this quest for quite a long time, as we use the typical solution of selecting PS candidates by choosing
1.Amp Stab. 1-sig/mu, which is a modified version of amplitude dispersion index. What about other choices?
2.RCS, is that for the ratio of clutter and signal?
3.Temp-phase, is that for the phase dispersion index?
4.Amp Stab…[Read more]

I am running with your suggestion, it will take quite a while, hope it works.

I do not know why, but soft is plagued by some audio output error, and following by some errors of simulating noise statistics. Why could be the underlying causes, how could I solve it?

stevexu replied to the topic Concerning the results exporting in the forum Sarproz Forum 9 years, 1 month ago
I know the reason, it seems SARproz does not calculate the deformation velocity if you use non-linear estimation mode(as smart 5). I rerun the APS step and the SPP step using linear estimation, now the result is obtained.

stevexu replied to the topic Concerning the results exporting in the forum Sarproz Forum 9 years, 1 month ago
If you are right, then why the velocity was not generated after the step of SPP processing was done? I rerun the SPP step, still not result.
-
stevexu replied to the topic Concerning the results exporting in the forum Sarproz Forum 9 years, 1 month ago
I rerun every single step since co-registration, though time consuming, still no result. It seems the vel.mat is not generated in the APS step. Why does it happen?

The sub scene has been successfully processed, however, I got troubles in the sparse geocoding steps. Something wrong with the index, I reset the steps but still got hooked. Detail goes as shots below:

You are quite right, I did not discern the host address is changed due to the wireless internet reconstruction in our department, now I changed to the wire internet, it works smoothly. Thoroughly thanks!

I crop the area smaller, which up to 5000 * 6000 pixel, but it still frozen there, since I set the DL=0, the top command shows only one eternal occupied process is by MATLAB, though somehow parallel MATLAB workers show sometime.

I use top, only one matlab process is running, as describe below:
That was strange, it has occupied only 5% of CPU

Thanks for you attention, the Matlab parallel pool is still busy, but waitbar is still 0%.

Yeah, you are quite right, I reset the parameters as your recommendation, in which:
1. DL=0;
2. Linear trendI am using a dataset mainly located in the urban area, I re-run the “Sparse Point Selection” and “Graph Creation”, but stopped at “Connection Processing”, the runtime window shows as below
