The radar antenna has a high CAPTURE cross-section. It is
designed to be verry efficient at transmitting and receiving radar
signals at design wavelengths. Unless there is a reason, what happens
at other wavelengths is left up for grabs because it is easier and
cheaper that way. What you have to avoid, is a retroreflector.
If you can avoid that, there shouldn't be much problem.
