    • An intruder detection system is provided in which a detection range can be set to a predetermined one so that false detection caused by a moving object outside the predetermined range can be diminished. The system includes a transmission-side leaky transmission line that radiates a detection signal for detecting an intruder and a reception-side leaky transmission line that receives a detection signal leaked from the transmission-side leaky transmission line, both of which are buried spaced apart from each other in a detection surveillance area, and detects the presence/absence of an intruder in the detection surveillance area based on variations in the detection signal received by the reception-side leaky transmission line, wherein at least part of either the transmission-side leaky transmission line or the reception-side leaky transmission line is made of a surface-wave-type leaky coaxial transmission line, and the other leaky transmission line, a radiation-type leaky coaxial transmission line.
    • 提供一种入侵者检测系统,其中可以将检测范围设置为预定的检测范围,从而可以减少由预定范围之外的移动物体引起的错误检测。 该系统包括发射侧泄漏传输线,其辐射用于检测入侵者的检测信号和接收侧泄漏传输线,其接收从发送侧泄漏传输线泄漏的检测信号,两者都被掩埋在与 在检测监视区域中彼此相对,并且基于由接收侧泄漏传输线接收到的检测信号的变化来检测入侵者在检测监视区域中的存在/不存在,其中发送侧泄漏的至少一部分 传输线或接收侧泄漏传输线由表面波型泄漏同轴传输线和另一个泄漏传输线,辐射型泄漏同轴传输线构成。
