StefanJAuer / RaySAR

RaySAR is a 3D synthetic aperture radar (SAR) simulator which enables to generate SAR image layers related to detailed 3D object models. Moreover, it enables one to localize the 3D positions and surface intersection points related to reflected radar signals. In particular, RaySAR helps to understand the nature of signal multiple reflections at man-made objects (e.g. building structures) or artificial shapes. Scene models with different levels of detail can be processed - from digital surface models (DSMs) to high-end 3D structures - which can be defined in relative or absolute world coordinates. RaySAR can be run on Windows / Linux and is based on an adapted version of the open-source ray tracer POV-Ray.

Dummy Python Parameters File #7

Open dannybrig opened 1 year ago

dannybrig commented 1 year ago

Hi there,

In the dummy python implementation for generating reflection maps, for the function 'raysar_function', there is an input variable "simulation_parameter_filename". It looks like this is the file where all the SAR sensor parameters are stored for things such as max bounce level, dB or clipping, etc. I'm wondering where exactly this file is located? The adapted povray gives me a contribution.txt output, but that seems to be used after this parameter file. How would we go about generating the "simulation_parameter_filename" and where would it be located?

Hi Daniel,

yes, the function is intended to search parameters from a SAR orbit meta file (here it was TerraSAR-X data). Please note that the format of the TerraSAR-X orbit file has changed in the meanwhile. Therefore, the search for keywords in the file needs to be adapted if you intend to work with TerraSAR-X data (there are supersites with open access to data: geoservice.dlr.de/eoc/ogc/stac/collections/SUPERSITES/items?f=text/htmlhttps://geoservice.dlr.de/eoc/ogc/stac/collections/SUPERSITES/items?f=text/html). To be honest, most often I visually copied the required parameters from the orbit file and started modeling. That is, I integrated the tool as some kind of template but did not really apply it in my simulation studies.

Regards Stefan
