A hyterdyne interference detecting system for long distance security pre-warning are introduced. Analyzed the generation principles of the multi-carrier phase-modulated signals, according to the purpose of signal processing, realized the intrusion event judgment and positioning by means of power spectrum analysis, extracted the modulated signals caused by(More)
Introduced a intrusion detecting system based on laser heterodyne interference technique. Analyzed the features of the multi-carrier phase-modulated signals from the detecting system, signal demodulation purpose and technical requirements are discussed, proposed the intrusion event judgment method by power spectrum analysis and realized the intrusion signal(More)
