Abstract

An active acoustic intrusion detection system includes a pair of dipole emitters (180 degrees out of phase with each other) which emit an audible frequency f (preferably 1 KHz) and a pair of detectors preferably mounted 1/4 wavelength (3 inches) apart in the (non-echoic) nulls of the emitters. The detectors (microphones) spatially sample a stationary wave which is generated by the emitters (speakers). The output of each microphone is fed to an ADC and the digital output of the two ADCs is used to generate a four dimensional vector. At startup, a reference vector is determined and stored. During operation, vectors are sampled, filtered, smoothed and averaged periodically. When an average vector deviates from the reference vector by a set amount, an alarm is generated.
