Beschreibung
Zusammenfassung:	The invention discloses an ocean island offshore defense monitoring system and method based on distributed optical cables. The system comprises a sensing optical cable, a sensing demodulation system, a data processing module and an upper computer, wherein the sensing optical cable is laid on an island reef shoreline and is used for detecting temperature change, vibration change and strain change of the position where the island reef shoreline is laid; the sensing demodulation system is used for providing an incident light signal for the sensing optical cable and receiving a scattered light signal returned by the sensing optical cable; the data processing module is used for resolving the scattered light signal received by the sensing demodulation system to obtain the temperature change, the vibration change and the strain change of the position of the island shoreline where the sensing optical cable is laid, and outputting the temperature change, the vibration change and the strain change as data processing re
