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 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, 12 months 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 10 years 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 10 years 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 10 years 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
