yeah, it seem a bit confusing but it show potentials
what I'd do:
the lines shouldn't go from the dots to the external, but the opposite, from the dots to the center.
Those lines shouldn't be complete, or it'd turn in a mess, I think that only a portion of the lines should be used, and you could use the lenght of the lines as an indicator of distance. A better distance indicator would be the luminosity of the dots, tho
Or, you could render only the horizontal plane (the same H plane of the pilot's ship) and use the lines to show the height of the dots from that plane
