OSCAR-Omni Spectral Correlator
|
 OSCAR
is a portable microcomputer controlled scanning spectral correlator.
It will scan from Audio (40Hz-15KHz), Radio VLF-Microwave
(10KHz-3000MHz) to infrared (850-1070nm) and utilize passive
sound-pattern matching to automatically recognize a surveillance
device. In the Automatic Mode, the unit will continuously scan all
bands for acoustic pattern correlation and then alert you to the
presence of a surveillance device by your choice of a silent alert or
audible one.
The Acoustic Correlator instantly recognizes complex sound patterns
arriving form both the reference and received audio channels. Most room
environments contain many "passive" sounds (air conditioners,
computers, talking, etc.) which OSCAR uses as an acoustic pattern match
between the rooms passive reference sounds and any identical information
received while scanning to provide you with a positive I.D. without
alerting the eavesdropper.
