WIDE-ANGLE, STATIC AND POSITIONAL ANTICIPATORY OBJECT DETECTION SYSTEM |
摘要 |
A wide angle, static, positional anticipatory object detection system (16) includes a transducer device (18) for transmitting a modulated carrier signal and receiving the modulated carrier signal reflected from an object, a detection device (22) for detecting a plurality of Doppler shifted harmonic components from the reflected modulated carrier signal, a range determining device (24) responsive to the amplitudes of at least two of the harmonic components being equal for determining the instantaneous range of the object, and a predetermined distance thereafter, to a predeterminded difference between the amplitudes of at least two of the harmonic components. The system (16) also includes a Doppler period measurement device (26) responsive to at least one of the harmonic components for measuring the Doppler periods of that harmonic component and a collision decision device (28), responsive to the range determining device (24) and the Doppler period measurement device (26), for indicating that a collision with the object is imminent and the offset of the collision from the detection device (22) before contact is made. |
