short version

The article deals with the multiple reflection of microwaves on artificial objects such as airplanes, cars or ships. The multiple reflection can significantly affect the RCS values ​​of such objects. Probably the most important mechanism is double reflection, and this is the focus of this presentation. We are interested in the high frequency case, i.e. that the wavelength is significantly shorter than the dimensions of the scattering object, and under these circumstances the beam optics are typically used to simulate the multiple reflections. This lecture shows that under certain conditions the use of beam optics can lead to considerable errors, which makes the use of the physical-optical method necessary.
