Abstract
A self-implementing, self-diagnostic system for an anticipatory collision sensor system includes a transducer device for transmitting a modulated carrier signal and receiving the reflected modulated carrier signal from an object; a detection device for detecting a plurality of Doppler shifted harmonic components from the reflected modulated carrier signal; a range determining device responsive to the amplitude of at least two of the harmonic components for determining the instantaneous range of the object; a velocity measurement device, responsive to the frequency of at least one of the harmonic components, for determining the relative, instantaneous velocity of the object; an indicating device, responsive to at least one of the modulated carrier signal, the reflected modulated carrier signal, the amplitude, and the frequency, to indicate the condition of the system.
