Abstract
A multi-sensor anticipatory object detection system for detecting the instantaneous range, relative velocity, collision angle and point of impact of a colliding object includes a plurality of transducer devices angle a fixed distance in which each said transducer device transmits a modulated carrier signal and receives the reflected modulated carrier signal from an object; a detection device for detecting a plurality of Doppler shifted harmonic components from each said reflected signal; a range determining device, responsive to the amplitudes of said harmonic components, for determining the instantaneous range of said object from each said transducer device; a velocity measurement device, responsive to the frequency of said harmonic components, for determining the relative instantaneous velocity of said object; and an impact decision device, responsive to said range determining device and the velocity measurement device, for determining where, if at all, impact with the object will occur and the angle of the impact prior to impact with the object.
