摘要： The present invention relates to a method and apparatus used to calculate at least one velocity component for a target within the region. The invention employs an energy source which is activated using an activation system in a cyclic pattern with a selected source frequency. A receiver is also employed in conjunction with a shielding system where this shielding system is configured to block the sensing of reflected energy from the target in a cyclic pattern with a selected receiver frequency. The invention operates through measuring a frequency change in the source frequency of the energy source signal when received by the receiver and determines a velocity component for a target based on a measured frequency change for a known direction of travel. The invention may also be extended to provide a two or three dimensional velocity vector through the addition of further energy sources.

摘要： The invention relates to a solid-state range sensing system. As with previous solid-state range sensing systems, an energy source is activated and deactivated in a cyclic pattern with a selected source frequency. A receiver is adapted to sense the reflection of emitted energy from the target. The receiver includes a shielding system to block the sensing of the reflected energy from the target in a cyclic pattern with a selected receiver frequency. Unlike the prior art, the frequency of the source and receiver are offset by a small frequency. The resulting output signal of the receiver is a further cyclic pattern beat signal of frequency equal to the difference between the source activation and receiver shielding modulation frequencies. The best signal is effectively a down-converted version of the source modulation frequency and, unlike the prior art, is compared with a reference beat signal whereby the phase difference between the two beat signals is used to determine a range value. The use of beat signals provides higher precision than the prior art.
