snap_graph.BackscatterConfig

Settings shared by the backscatter pipelines, RTC and GTC.

Usage

Source

snap_graph.BackscatterConfig()

Abstract: pass RTCConfig for terrain-flattened gamma-0 backscatter or GTCConfig for beta-0 backscatter that is geocoded only. Inherits every parameter of GeocodingConfig.

Parameters

multilook

(n_rg_looks, n_az_looks) applied after TOPSAR-Deburst, before terrain flattening; None skips the Multilook step. Multilooking here cuts runtime sharply, because the reduced raster passes through both terrain flattening and terrain correction.

SNAP’s grSquarePixel option, which derives the azimuth looks from the range looks and the local geometry and discards the requested n_az_looks is pinned off. Therefore, the looks given are the looks applied.

Usage

to_xml(*, snap_version=None)

Takes snap_version for a uniform signature; only the coherence graph has options that depend on it, so it does not change this one.
