Enhance SARDeburst

Summary

New Mode for SARDeburst application and two new applications into OTB : SARBurstExtraction and SARConcatenateBursts.

Rationale

This new mode and applications will be used by some processing chains such as DiapOTB chain for IW S1 products.

Implementation Details

Classes and files

Three classes was changed :

• ossimSarSensorModel : New functions and spread deburst function to include a new mode (onlyvalidsamples : keep into debursted image only valid samples).
• otbSarSensorModelAdapter : New interfaces for ossimSarSensorModel functions.
• otbSarDeburstImageFilter : New mode onlyvalidsamples.

Two filters have been added :

• otbSarBurstExtractionImageFilter
• otbSarConcatenateBurstsImageFilter

Applications

One application has been changed and two have been added:

• otbSARDeburst : New mode to keep only valid samples into output image.
• otbSARBurstExtraction : New application to extract all bursts or one selected burst from an IW S1 image.
• otbSARConcatenateBursts : New application to concatenate and deburst a list of bursts (IW S1 products).
