we found out that the timing of the image was decreasing.
new pcodes are already available online with the fixed version -

yes, the image is flipped, my version is 19-Sep-2015 09:47:45 due to version manager the newest one

is the image flipped? are you using the most recent updated version of sarproz?

Hi,
while processing RSAT-2 images I get wrongly geocoded reflectivity map (). Attached please find screenshots in chronological order.
Thanks

yyyymmdd.led file size is different from the original. After replace the led file, it works now.

cnu_lee replied to the topic user defined DEM in the forum Sarproz Forum 9 years, 2 months ago
Thanks for the help from Pro.Daniele and Dr. yuxiao. The problem has been solved.
Firstly,ensure the DEM is bigger than research area. The research area should be checked carefully. It must be smaller than the user defined DEM, or it will not be processed successfully follow-up.
Secondly, the problem is coordinates transformation.My first-time…[Read more]

right, for some reasons I forgot to answer.
Well, the easiest way for you to select manually points is to create manually a mask file.
You can do it in the following way:
– type fast in the matlab command prompt
– create vectors of samples and lines of the points you want to analyze:
Svet=[ … ]; Lvet=[ … ];
– create a matlab sparse matrix:…[Read more] -
periz replied to the topic amplitude values in the forum Sarproz Forum 9 years, 2 months ago
Images are equalized via a simple normalization process.
You need it to perform statistics on amplitude time series.
The unit of amplitude is volt. But its value is useful only if compared to other values, not in an absolute way.
If you could calibrate it by knowing the amplitude of a reference corner reflector,
you could derive the RCS of targets…[Read more] -

First of all,
can you update the software version?
You do it through the manage version module, in the dataset selection window.
Then try again and if the problem persists, can you send us a link for downloading your LED file? -

I am afraid we need to check the data together
Can we talk on skype? -

Daniele,
could you please answer the questions from the previous one-week-old post in this thread?
Thank you, Ivana

ivca-cz started the topic amplitude values in the forum Sarproz Forum 9 years, 2 months ago
Hello,
I would like to ask in what units are the amplitude values. As these values (up to 4 for most of the area, high-amplitude points up to 30-40) do not seem to be the absolute values (expecting to 10^3, high-intensity points up to 10^8), neither the decibels (or decibels w.r.t. what?).
Thank you, Ivana

Hi Huijung,
you need to zip the attachment before uploading them.
Can you also upload them again?

Can you also include the lasterror.mat file?
