4.2 Beams & geometry
The southward pointing beams will intersect a meteor trail at an altitude of about 90km and a Doppler-shifted return will be scattered in many directions. Some portion of the scattered return will arrive at the receive antenna as shown in Figurę 4.4
Figurę 4.4 Reflection from a meteor trail
The detailed geometry of the interaction of the Graves beams with a meteor trail is shown in Figurę 4.5. The total rangę from the meteor trail to the receiver is ~1100km.
