Binaural Automobile Radar 750089

The antenna configuration of a radar crash sensor determines in large part the kinematic measuring capabilities of such a sensor. Simple monostatic and bistatic antennas have limited collision estimation abilities which can potentially be overcome by a binaural system. The theoretical characteristics of a binaural radar have been used to optimize the collision estimation abilities for point target obstacles. Measurements with obstacles of small lateral extent are in good agreement with theory. Measurements with obstacles of large lateral extent do not agree with simple point target theory due to detection of different scattering centers by the two bistatic arrays of the binaural radar. Methods of minimizing this problem are discussed.
