SARCorrelationRough

Computes SAR correlation shift (rough shifts).

Description

This application comutes rough shifts between two images : shift in range and shift in azimut. The inputs of this application are MultiLooked images (real images).

Parameters

Input Master image (real image) -inmaster image Mandatory
Master Image (real image).

Input Slave image (real image) -inslave image Mandatory
Slave Image (real image).

MultiLook factor on distance -mlran int Default value: 3
MultiLook factor on distance.

MultiLook factor on azimut -mlazi int Default value: 3
MultiLook factor on azimut.

rough shift in range dimension into SLC geometry (output of this application) -shiftranslc float Default value: 0
rough shift in range into SLC geometry.

rough shift in azimut dimension into SLC geometry (output of this application) -shiftazislc float Default value: 0
rough shift in azimut into SLC geometry .

rough shift in range dimension into ML geometry (output of this application) -shiftranml float Default value: 0
rough shift in range into ML geometry.

rough shift in azimut dimension into ML geometry (output of this application) -shiftaziml float Default value: 0
rough shift in azimut into ML geometry .

Available RAM (MB) -ram int Default value: 256
Available memory for processing (in MB).

Examples

From the command-line:

otbcli_SARCorrelationRough -inmaster s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_ML.tiff -inslave s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002_ML.tiff

From Python:

import otbApplication

app = otbApplication.Registry.CreateApplication("SARCorrelationRough")

app.SetParameterString("inmaster", "s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_ML.tiff")
app.SetParameterString("inslave", "s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002_ML.tiff")

app.ExecuteAndWriteOutput()

Limitations

Only Sentinel 1 (IW and StripMap mode) and Cosmo products are supported for now.
