There's no need for radar.  Coming out of jump space (in multiple
rulesets) produces a bright EM "flash" across a broad range of
wavelengths.  If a sensor system can't get a bearing on that to within
at most a square arcsecond, it's not worth the cardboard it was made
from.

Given at least one ruleset, the jump flash is visible *without
instruments* at a million kilometres, which is roughly 100D range for
terrestrial planets
