SARDeburst - SAR Deburst

This application performs a deburst operation by removing redundant lines.

Detailed description

This application performs a deburst operation by removing redundant lines between burst. This operation is useful when dealing with Sentinel1 IW SLC products, where each subswath is composed of several overlapping burst separated by black lines. Lines to remove are computed by SAR sensor model in OSSIM plugins. The output image is smaller in azimuth direction than the input line, because of removed lines. Note that the output sensor model is updated accordingly. This deburst filter is the perfect preprocessing step to orthorectify S1 IW SLC product with OTB without suffering from artifacts caused by bursts separation.

Parameters

This section describes in details the parameters available for this application. Table [1] presents a summary of these parameters and the parameters keys to be used in command-line and programming languages. Application key is SARDeburst .

Example

To run this example in command-line, use the following:

otbcli_SARDeburst -in s1_iw_slc.tif -out s1_iw_slc_deburst.tif

To run this example from Python, use the following code snippet:

#!/usr/bin/python

# Import the otb applications package
import otbApplication

# The following line creates an instance of the SARDeburst application
SARDeburst = otbApplication.Registry.CreateApplication("SARDeburst")

# The following lines set all the application parameters:
SARDeburst.SetParameterString("in", "s1_iw_slc.tif")

SARDeburst.SetParameterString("out", "s1_iw_slc_deburst.tif")

# The following line execute the application
SARDeburst.ExecuteAndWriteOutput()

Limitations

Only Sentinel1 IW SLC products are supported for now.
