Path: Link/Coverage
% Determines if a satellite is visible to an ISL.
Any number of satellites can be tested against any number of boresights
on a satellite. The output is the distance of the target from the
satellite when the target is within the angle specified by a3dB.
The output is a cell array of 1 by n vectors.
Type ISLFOV for a demo. In the demo one spacecraft is
in the same orbit and displace by pi/16. The other is in a lower orbit.
The boresight vectors point at the two targets at the start.
