Abstract
A radar presence detection system is configured to detect oscillations within a building. The radar presence detection system includes an accelerometer, a radar, and a processing unit. The accelerometer is attached to the building and configured to detect structural vibration waves. The radar is configured to transmit a monitoring wave and receive a reflected wave. The processing unit includes a filter, an adaptive filter, and a detector. The filter is configured to receive a first signal indicative of the reflected wave and output a filtered reflected wave signal spanning a frequency range indicative of an oscillation within the building. The adaptive filter is configured to receive a second signal indicative of the structural vibration wave signal and output a focused vibration signal spanning a frequency range for the cancellation of vibration noise.
