You might want to process the Sentinel-1 data in a simple and efficient way, but meet the following two issues:
1. Your region of interest (ROI) spans two adjacent Sentinel-1 frames, but you do not want to process them separately.
2. The Sentinel-1 file is too big for your ROI, and you do not want to process the entire swath or frame.
The GITASAR might give a solution, please check out "Coregistration" --> "Sentinel-1" -->"Sentinel-1 Merge" and "Sentinel-1 Crop" which will deal with the raw Sentinel-1 data to generate a new Sentinel-1 file in raw format.
 
I found that my alos-2 data is in the spotlight mode. I can't find 'spotlight' in 'import'. Although it didn't solve my problem, I still thank you for answering it for me
 
Hello, I want to execute KZ calculation after importing the image, but the tool is forced to exit after clicking OK. Has anyone else encountered this situation?I use spotlight data. When importing, I use "alos2 stripmap", which can generate ". XML" results. Does this have an impact on forced exit?

1. Bursts and Polarizations can be designated for the coregistration of Sentinel-1 SLC for the purpose of PolInSAR applications in future. Please check out "InSAR" -> "Coregistration" -> "Sentinel-1"
2. Add Ionospheric phase delay estimation for long-wavelength SAR systems such as L-band PALSAR-2. Please check out "InSAR " -> "Ionospheric phase delay estimation".

Beta version of the GITASAR with parallel processing is uploaded.
Functions with parallel processing include "Resample", "Geocoding", "Local IA calculation", "SAR simulation" etc. Welcome to test! and have Fun!

If you want a portable and easy use tool to process the SAR data, GITASAR might give you an option. Written by C/C++, python and worked on X64 PC under multiple threads, it includes the following key features:
1. Import: Support RADARSAT-2, PALSAR-2 L1.1, PALSAR-2 L1.5 CEOS, TerraSAR-X, Sentinel-1 SLC, and UAVSAR GRD products.
2. Basic processing: Incidence, local incidence angle calculation, oversample, and multilook etc.
3. Correction: SAR Filtering, SAR DEM Boundary Estimation, and SAR Geocorrection (including Sentinel-1 SLC and GRD) etc.
4. InSAR: 4.1 Coregistration where Bursts and Polarization can be designated for the Sentinel-1 SLC.
4.2 Sentinel-1 raw .SAFE file merging and cropping
4.3 FLAT EARTH and DEM phase estimation.
4.4 interferogram filtering and coherence.
4.5 Ionospheric phase delay estimation.
5. PolSAR: S2 to T3 and C3, model-based decomposition, and soil moisture Estimation etc.
6. PolInSAR: Kz calculation, optimum coherence, forest height, and soil moisture estimation etc.
NOTE:
1. The DEM used in the GITASAR must be in ENVI format with WGS94 projection and Float datatype. If you have installed GDAL, you can use "SAR Import" --> "Import DEM" for the converting.
2. Please email xhuang@appliedgeosolutions.com for more info.
