# RT1 - bistatic scattering model for first order scattering of random media
----
> [!CAUTION]
> **This package is superseeded by a [TUW-GEO/rt1_model](https://github.com/TUW-GEO/rt1_model)!**
> ([TUW-GEO/rt1_model](https://github.com/TUW-GEO/rt1_model) provides similar functionalities but with a simplified and more robust API)
----
The package implements a first order scattering radiative transfer model
for random volume over ground as documented in *Quast & Wagner (2016)* and
*Quast, Albergel, Calvet, Wagner (2019)*
The documentation of the package is found [here](http://rt1.readthedocs.io/).
(Note that the documentation is still under construction.)
## Overview of the RT1 python-module structure
- 🏞️ **rt1.volume** and **rt1.surface**
- a collection of useful surface- and volume scattering distribution functions
- 🔨 **rt1.rt1**
- generic implementation of radiative transfer calculations for a random
volume over ground
- symbolic evaluation of first-order interaction contribution estimates
- ⚙️ **rt1.rtfits**
- a flexible interface to perform parameter estimation from incidence-angle
dependent backscatter-timeseries via non-linear least-squares fitting routines.
- integrates with a set of pre-defined plot-functions and interactive
widgets that can be used to quickly analyze the obtained results
- :rocket: **rt1.rtprocess**
- a versatile interface to setup and run parallelized processing
- 📑 **rt1.rtparse**
- a configparser to set up processing-routines via .ini files
## Usage
Any usage of this code is subject to the following conditions:
❗ Full compliance with the license (see LICENSE file) is given
❗ In publications or public presentations, credit should be given to the
authors by:
- citing the references below ✔️
- pointing to this github repository ✔️
## Installation
For a basic install, the following line should be fine:
pip install rt1
In order to get a significant speedup in the symbolic computations and enable
NetCDF functionalities, it is recommended to install the module with the
optional dependencies `symengine` and `xarray` by using:
pip install rt1[full]
