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.

how to set up parameters to correct these scatterer signals to match them to the correct position with the 3D model #15

Dear Professor， image image image image

I used the simulation tools for exporting the 3D distribution of scatterers. However, it was not possible to match the scatterer signals to the AccuTrans 3D model, and their positions were greatly offset.I don't know how to set up parameters to correct these scatterer signals to match them to the correct position with the 3D model.Could you give me some advice?

Thanks and Regards HuangKesheng

Dear Huang Kesheng,

when exporting the 3D distribution of scatterers from POV-Ray coordinates (-> context: POV-Ray model) into the world coordinates of the original (-> context: CAD-type model) model you need to compensate for the rotations and shifts you applied in the POV-Ray editor in the context of the #include command. I’d assume that this yields the mis-match.

Regards Stefan Auer
