摘　　要：针对边境地区自然环境恶劣、监控盲区较多、管理人员有限等问题,为提升边境管理单位的管控能力,研发了一种融合布里渊光时域反射仪(Brillouin optical time-domain reflectometer,BOTDR)和相位敏感型光时域反射仪(phase-sensitive optical time-domain reflectometer,Φ-OTDR)的分布式光纤声学传感(fiber-optic distributed acoustic sensing,DAS)设备,实现了单一设备多参量同步测量。该系统利用先进的信号处理算法,能够动态感知环境声场能量变化,精确识别和预警入侵行为。通过一系列实验验证了系统的有效性和可靠性,可为未来边境地区建立无人化、智能化警戒防卫体系提供参考。In response to the challenges faced by border areas,such as harsh natural environments,numerous monitoring blind zones,and limited management personnel,a fiber-optic distributed acoustic sensing(DAS)device that integrates Brillouin optical time-domain reflectometer(BOTDR)and phase-sensitive optical time-domain reflectometer(Φ-OTDR)has been developed to enhance the control capabilities of border management units.This device enables synchronous multi-parameter measurement with a single piece of equipment.Leveraging advanced signal processing algorithms,this system can dynamically perceive changes in environmental acoustic field energy,accurately identify and issue early warnings for intrusion behaviors.A series of experiments have verified the effectiveness and reliability of the system,providing a reference for establishing unmanned and intelligent warning and defense systems in border areas in the future.
