A shot in the dark here, but it sounds like the mast is just to get the Shuttle
out of the near firld of the transmitter/receiver. If it is really SAR then the
mast has nothing to do with the baseline. The baseline is the distance the
shuttle has traveled between sending and recieving. Thus, "Synthetic Aperture"
RADAR. The image is built up based on how many times you 'ping' the target. In
fact, a target can be "spotlighted" by aiming at it as you go by for even
better resolution.
By the way, if you look at the geometry you will see that the farther to the
side of your path something is, the more times it is hit as you go by. It is
linear, and therefore the resolution is independent of range, which is pretty
darn cool.
