Abstract: In a vehicular harmonic radar detecting and ranging system, a transmitter transmits a highly directional and polarized beam of electromagnetic energy, preferably in the microwave spectrum, toward a passive target. The passive target reradiates a beam of energy, which is harmonically related to and polarized orthogonal to the transmitted beam, directionally back toward the transmitter. A receiver by being selectively responsive the the harmonically related and orthogonally polarized reradiated beam, is immune to blinding which would otherwise be caused by the transmitted signals of other radar equipped vehicles and to the clutter caused by extraneous targets.
