摘　　要：提出将混沌相关探测方法与泄漏电缆导波雷达技术相结合,设计实现了一种基于LabVIEW平台的混沌导波雷达样机,用于实现安全防护区域的高分辨率非法入侵探测。该雷达采用宽带布尔混沌信号作为探测信号,利用稀疏编织型泄漏电缆实现混沌信号的发射与接收。基于LabVIEW平台实现雷达系统控制,包括控制数据采集卡采集参考信号与回波信号,对两路信号进行相关计算得到相关曲线,以及对比入侵前后的相关曲线从而确定入侵者沿泄漏电缆的入侵距离。实验结果表明,该雷达不仅可以实时监测入侵过程,还可同时定位多个入侵者。距离分辨率可以达到50 cm,优于现有导波雷达米量级的分辨率。测量的动态范围可以达到35 dB。因此,混沌导波雷达可以为安全防护区域的非法入侵探测提供一种高分辨率、大动态范围的新方法。We propose to combine the chaotic correlation detection method with leaky coaxial cable(LCX)guided radar technology,then design and implement a chaotic guided radar prototype based on the LabVIEW platform,which is used to detect the illegal intrusion of security protection areas with high resolution.The proposed radar uses the wideband Boolean-chaos signal as the probe signal,and then utilizes the sparsely braided LCXs to transmit and receive the chaotic signal.Based on the LabVIEW platform,radar system control is realized,including controlling the data acquisition card to collect the reference and echo signals,calculating the correlation trace of these two signals,and comparing the correlation traces before and after intrusion to determine the intruder’s distance along the LCXs.The experimental results demonstrate that the proposed radar can not only monitor the intrusion process in real time,but can also locate multiple intruders simultaneously.The range resolution can reach 50 cm,which is superior to the meter-level resolution of the existing guided radars.The dynamic range of measurement can reach 35 dB.Therefore,the chaotic guided radar can provide a new method with high resolution and large dynamic range for detecting the illegal intrusion of security protection areas.
