Collision Avoidance

ABSTRACT

The positioning of the BIMA antennas in compact array configurations
for CARMA introduces scenarios where collisions between adjacent
antennas are possible.  This document reviews these scenarios in a
purely geometrical context, defining ``exclusive regions'' between
adjacent antennas where only one will be allowed to traverse at a
given time.  These regions may be used to develop algorithms for
moving antennas in a manner that will avoid collisions.
