Abstract:
A radar detector for airbag triggering prior to a collision between a vehicle on a roadway and an impacting target object, comprising:at least one set of transmitting and receiving antenna means, each said transmitting antenna being longitudinally spaced apart from said receiving antenna means, wherein each said transmitting antenna is mounted to one side of a transverse centerline passing approximately orthogonal through the longitudinal axis of said vehicle and each said receiving antenna is mounted to the opposite side of said transverse centerline;mounting means for adjustable support of each said transmitter antenna means and said receiver antenna means so as to provide a uniform bistatic antenna pattern coverage of one or more sides of said vehicle;at least one set of transmitter and receiver means, each said transmitter means being electrically connected to a respective transmitting antenna, and each said receiver means being electrically connected to a respective receiving antenna;means for detection of a signal out of said receiver means, said signal resulting from radiation from said transmitter antenna being reflected from an object adjacent the side of said vehicle;signal processing means for continuous tracking of the position of said target object relative to the side of said vehicle;computer means for continuous calculation of the predicted time and point of impact, andmeans for controlling initiation of an airbag at a predetermined time before impact between said object and the side of said vehicle.
