The first study regards the bistatic RCS response to a
X-band, 10 GHz signal (frequency where most onboard
radars operate). For that, the incoming plane wave is
assumed to be incident right on the frontal side of the
missile (90º in the Fig. 5), with the electric field aligned to
the missile longitudinal axis, as Fig. 5 suggests. The results
of the bistatic RCS is also shown in Fig. 5. It can be seen
that the frontal RCS has a value of -9.6 dBSm.
