Four semispheres will be generated to model the radome as a thin layer approximation.
It may be achieved by using the sphere command, which requires both the
center and the radius. The table below shows the parameters to be used for every
sphere:
Sphere

Y (mm)
Z (mm)
Radius (mm)

Note that the sphere command creates the full closed sphere and we need just the
upper semisphere. Then, after creating each sphere, we use the explode command to
separate it in several surfaces, then remove the lower semisphere with the
delete command, and finally we use the group command on the upper
remaining surfaces to have one object for every semisphere.

After creating the four semispheres, in the tree we can see that they have been added
in order as Objects, and each one has a different name.
