EP-95 ON THE MOON WITH APOLLO 16
FIGURE 72.- Bistatic Radar Experiment.
The radio communication signals from the spacecraft travel along two
paths. One comes directly to the receiving antennas on Earth. The
other travels to the Moon is reflected, and then travels directly to
the receiving antennas. comparison of these two signals allows us to
recognize the changes caused by the reflection from the Moon. quell
changes are the basic data of this experiment from which we infer the
electrical properties of the outer few yards of the Moon. The Moon
and spacecraft are not shown to the same scale.
