MOTION DETECTOR |
| 摘要 |
The present invention relates to a motion detector using the Doppler shift principle. The received signal may be a Doppler shifted version of a transmitted signal. Combining the phase and/or amplitude shifted version of the received signal and the signal from the local oscillator produces an IF signal that is indicative of the phase and/or amplitude shift.
