Convert SAR Units (Image Analyst)

This ArcGIS 3.0 documentation has been archived and is no longer updated. Content and links may be outdated. See the latest documentation.

Available with Image Analyst license.

Summary

Converts the scaling of the input synthetic aperture radar (SAR) data between amplitude and power and between linear and decibels (dB).

Usage

  • This tool simplifies SAR product interpretation and improves image display by reducing the range of amplitude or intensity values through the conversion to a dB value.

  • You can also convert data from amplitude to power and vice versa.

Parameters

LabelExplanationData Type
Input Radar Data

The input radar data.

Raster Dataset; Raster Layer
Output Radar Data

The converted radar dataset.

Raster Dataset
Conversion Type
(Optional)

Specifies the type of backscatter conversion that will be applied.

  • Linear to dBThe unitless value will be converted to decibels (dB) values. This is the default.
  • dB to linearThe dB values will be converted to unitless values.
  • Amplitude to powerThe amplitude values will be converted to power values by squaring the amplitude.
  • Power to amplitudeThe power values will converted to amplitude values by applying the square root to the power.
