Abstract

The electromagnetic wave attenuation characteristics of two common construction materials, specifically C30/37 concrete and aerated-concrete, namely C30/37 concrete and aerated concrete, have been investigated due to their importance in rubble-penetrating radar-based life-sign detection. This paper presents the results from radar experiments using free-space vector network analyzer measurements within the $400 - 1400$ MHz frequency range, aimed at monitoring periodic arm movements behind wall blockages made of these materials. To ensure data validity, tests were carried out with two different antenna types: the Vivaldi tapered slot antenna and the double-ridged horn antenna. The reflection data collected at a fixed sensor position were processed by eliminating the static background and averaging the results. The received power levels and frequency variations of the resultant change data were evaluated and compared in relation to the electromagnetic absorption characteristics of the examined concrete samples.

400 - 1400mhz范围内变化信号穿越混凝土屏障反射衰减的测量与分析

考虑到C30/37混凝土和加气混凝土两种常见建筑材料在破石雷达生命信号探测中的重要性，本文对C30/37混凝土和加气混凝土的电磁波衰减特性进行了研究。本文介绍了利用自由空间矢量网络分析仪测量400 - 1400 ${\bf{400}}-{\bf{1400}}$ MHz频率范围内的雷达实验结果，旨在监测由这些材料制成的墙壁障碍物后的周期性手臂运动。为了确保数据的有效性，使用两种不同的天线类型进行了测试：Vivaldi锥形槽天线和双脊喇叭天线。在固定传感器位置采集的反射数据，通过消除静态背景并对结果进行平均处理。所得变化数据的接收功率水平和频率变化进行了评估，并与所检查的混凝土样品的电磁吸收特性进行了比较。
