# RCS of a corner reflector¶

This is example shows how to use RadarSimPy to simulate the RCS of an object based on its 3D model.

The corner reflector model is with .stl. It can be imported by using meshio module.

### RCS vs frequency¶

Define the basic parameters required in ray tracing.

• Observation angle phi (Degree)
• Observation angle theta (Degree)
• Frequency freq (Hz)
• Polarization pol
• Ray density density (number of rays per wavelength)
