it can detect signals that come from behind you, but only does so by radar waves bouncing off the windshield and hitting the front receptor (which is less than ideal).
Valentine holds a patent for radar detectors with front AND rear receptors, so it's the only one that has it in both places (if I'm not mistaken). it is the presence of both receptors that allows the V1 to determine if the signal is in front of or behind you (timing difference between when the signal hits the front and rear).
