Hey there,
I want to compare the results of simulating an object (in this case, a wall) against the same simulation but using the RCS of the same object.
The issue comes when considering the RCS. Theres a parameter under the "Database" tab in the project parameters section. Here I tick the box that says COnsider RCS information and then import the file.
I'm using a "flat" simulation area that encompasses an area of 4x4 meters with a 0.1m resolution. However, while I get a representation of the returned signal when using the physical object (as expected), when using the RCS I just get a single "bit" or "square" (0.1x0.1 point) of the equivalent resolution on the corner of this simulation area.
What should I consider to get an accurate result?
I already tried to change the RCS azimuth value with no success. And the steps I followed were provided in an example from Altair
Thanks in advance
When you have one flat panel, that is oriented correct to reflect back to the radar like a mirror, then the two approaches should give comparable results (although the approach with RCS may average over a small range of angles, depending on the details of the setup).
When you have a more general geometry, then it becomes more complicated. When you have the geometry explicitly in WinProp, you need to activate scattering for all the parts that are not oriented as described above. The question is then how to choose scattering parameters. In such a general case, importing the RCS from Feko is probably better.
