Incident-wave series
Monostatic Radar Cross Section
The goal is to plot the monostatic radar cross section (RCS) as a function of angle for a
scattering object, as shown in the figure below. The scattering object is a so-called corner
reflector: three sheets of metal connected at right angles to each other. A corner reflector
is often used as a calibration object in radar experiments. It has the advantage of a large
RCS over a wide angular range. In the example project, symmetry has been exploited
with respect to the XZ plane.
Corner reflector
To produce a plot of monostatic RCS through measurements, usually the incident wave is
constant and the scattering object is rotated. In the numerical simulation, however, the
scattering object is stationary and a collection of incident waves strikes it from many
directions. In this case, we want incident waves whose directions of incidence vary from
θ=0 to θ=360 degrees in the φ=0 plane. To visualize this, imagine the transmitting and
receiving antennas going full circle in the XZ plane around the object, while always
being directed towards the scattering object. The polarization is chosen to be in the φ
