SARDEMToAmplitude

Simu_SAR step for Diapason chain.

Description

This application executes the Simu_SAR step with three internal applications : SARDEMProjection, SARAmplitudeEstimation and SARMultiLook.

Parameters

Input DEM -indem image Mandatory
DEM to extract DEM geometry.

Input SAR image -insar image Mandatory
SAR Image to extract SAR geometry.

Output simulated amplitude Image (this output image is multilooked) -out image [dtype] Mandatory
Output simulated amplitude Image (this output image is multilooked).

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

No Data values for the DEM -nodata int Default value: -32768
No Data values for the DEM.

Averaging on distance -mlran int Default value: 3

Averaging on azimut -mlazi int Default value: 3
Averaging on azimut

Gain to apply on ML image -mlgain float Default value: 1
Gain to apply on ML image

Examples

From the command-line:

otbcli_SARDEMToAmplitude -indem S21E055.hgt -insar s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff -out s1a-s4-simu-amplitude.tiff

From Python:

import otbApplication

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

app.SetParameterString("indem", "S21E055.hgt")
app.SetParameterString("insar", "s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff")
app.SetParameterString("out", "s1a-s4-simu-amplitude.tiff")

app.ExecuteAndWriteOutput()

Limitations

Only Sentinel 1 products are supported for now.
