## snap_graph.RTCConfig


Configuration for terrain-flattened backscatter (RTC).


Usage

``` python
snap_graph.RTCConfig()
```


Gamma-0 backscatter, radiometrically terrain corrected: called Normalised Radar Backscatter (NRB) in CEOS-ARD and RTC-S1 by OPERA. The product also carries the local scattering area that terrain flattening divides by. Inherits every parameter of [BackscatterConfig](snap_graph.BackscatterConfig.md#s1bursts.snap_graph.BackscatterConfig).


## Parameters


`dem_oversampling`  
DEM oversampling factor used by `Terrain-Flattening`. Must be positive.

`additional_overlap`  
Additional overlap percentage used by `Terrain-Flattening` when searching for terrain contributions outside the tile.
