Dear Prof. Daniel,
After I read your answers, I tried some experiments with GAR to comprehend better in the past days. I got some more questions here during the experiments:

1. Does GAR always behave better than MISP? And do you recommend to use GAR in most cases?

2.You mentioned GAR could detect strong movements which exceeds wavelength, I…[Read more]

Hi,

When I use the Graph Analysis module as well as read the manual, I come up with the following questions:

1. What the “Skip init Mask” means? When should it be checked?

2. As the NOTE 4 in manual says:”NOTE 4. in this module you can optionally save a time series object. However, for this purpose the atmosphere should have already been…[Read more]

I understand now. Thank you!

bridgetwang replied to the topic How to generate mean amplitude image in the forum Sarproz Forum 5 years, 7 months ago

Hi periz,

I have an additional question. As the manual says：“In case of 2 sensors analysis, two different Refl Maps are processed and saved. They are called respectively MeanFirst and MeanSecond”.

In case of different sensors, is it possible to generate only 1 mean amplitude image for the common AOI？ How to do it ？

thank you again for your…[Read more]

Dear all,

How can I generate a mean amplitude image after the PS stack images are co-registered？

Thank you for your help！

best regards,
Zoe

bridgetwang replied to the topic non-linear deformation question in the forum Sarproz Forum 5 years, 9 months ago

Thank you so much for your kindly answers. Now I know clearly that SarProz will give linear+nonlinear estimation at the same time when smart is choosen.

I have a further question here: For most cases, I have no prior knowledge of whether the deformation is linear or not. Then should I choose linear model first or nonlinear model first?

As I…[Read more]

Hello,

When I use the non-linear deformation processing, I got some questions even after reading the related discussions on the forum. Hope I can get your answers.

1、In sarproz, if “smart” is used, then linear deformation won’t be estimated. I want to know, is the linear deformation phase firstly removed from the interferometricc phase, and n…[Read more]

Thank you for the suggestion.

But how can I’ve never used the compiled version yet. Could you please tell me how to open the compiled version, and how to luanch the co-registration in more detail ?

Best regards

bridgetwang replied to the topic Sentinel-1A co-registration problem in the forum Sarproz Forum 6 years, 5 months ago

yes, this file exist. And the output of “license(‘test’,’Image_Toolbox’)” is 1

is this possibly a compatibility problem ?

hello forum,

I’m dealing with a Sentinel-1A dateset, but the co-registration failed.

The matlab reports :

Warning: Could not find appropriate function on path loading function handle C:Program FilesMATLABR2018atoolboximagesimagesprivateresampsep.mexw64>resampsep

Attached are the error files.

How can I get the problem solved?

bridgetwang replied to the topic Sentinel-1A coregistration problem in the forum Sarproz Forum 7 years, 6 months ago

Dear periz,

Thank you very much for the answer, I updated the software and the coregistration work successfully.But I didn’t find the log file for coregistration.

Also as I just complete the coregistration, although the matlab reports that the coregistration was concluded succesfully, I saw that for one image there is warning information. I put…[Read more]

Dear all,

I encountered with these warnings in the coregistration step for sentinel1-A.

Could you please tell me the reason and how to correct it ?

Thank you so much.

Hi,

I’m a user at univeristy. I came across the failure in downloading updates. I want to ask for the windows version, how to install the update software after downloading the psftp.exe ?
