本文提出了一种用于探地雷达成像的高密度线性渐变缝隙天线阵列的分辨率改进方法。在该系统中,我们使用的近场测量配置的壁LTSA阵列,并选择各种对的发射和接收天线的阵列元素。我们准备了四种选择模式,以便我们可以实际提高成像分辨率。我们消除了直接耦合效应,并补偿了由元件个体性和元件选择引起的光程波动。实验表明,该技术实现了更高的分辨率的图像采集,产生一个更清晰的分割杀伤人员塑料地雷结合自适应图像处理,基于复振幅纹理,即使在潮湿的红土土壤条件。
We propose a resolution improvement technique for a high-density array of walled linearly tapered slot antennas (LTSAs) in ground-penetrating radar imaging. In the system, we use the walled-LTSA array in a near-field measurement configuration and select various pairs of transmitter and receiver antennas out of the array elements. We prepare four selection modes so that we can practically enhance the imaging resolution. We remove the direct-coupling effect and compensate the path-length fluctuation caused by element individuality and element selection. Experiments demonstrate that the technique realizes higher resolution image acquisition to yield a clearer segmentation of antipersonnel plastic landmines in combination with adaptive image processing, based on complex-amplitude texture, even on a wet laterite soil condition.
