The live audio says that the LIDAR picked up a "stray" return from a
reflector on the JEM module. The reflector in question is not one which
Dragon is supposed to be "looking at".
Sounds like a classic "integration problem" which cropped up
unexpectedly.
Someone should go out and put some black tape over the bloody thing ;-)
That would be a good hardware solution, but a software solution should
be faster to implement. ;-)
The next Dragon should have a paint-gun g.
More seriously, rather than relying on reflectors, include modulated
light sources on the target - essentially laser pointers, modulated to
be unmistakable, with beam-spreaders, and the reflectors around them.
Or even give the sources IFF circuitry - Dragon pulsed "Numbers?" and
they reply "One", "Two", etc., as the case may be.
