探地雷达在地下生物量的系统非侵入性研究中具有很大的潜力。大约15年前的早期研究探索了这项技术的适用性，但仍然只有几个已发表的案例研究。非侵入性的根系特征为环境工程师、森林工程师、植物学家和植物科学家提供了有价值的信息。在这里，我们评估在Caatinga环境中进行探地雷达调查的采集参数，Caatinga环境是巴西独有的生物群(横跨东北部地区的八个州和东南部地区一个州的一部分)。这种生物群呈现出高密度的树木，使得系统的探地雷达测绘成为一项耗时的任务。在这个项目中，我们的目标是建立最实用的调查设计，包括空间抽样参数，以便在不影响数据质量的情况下优化调查效率。我们在高分辨率900 MHz探地雷达调查中探索了数据特征，面积为5×5米。根部图像显示与在试掘中观察到的生物量有很好的相关性。
There is significant potential for GPR to be applied to the systematic non-invasive study of underground biomass. Early studies, some 15 years ago, explored the applicability of the technique but there are still only a few published case studies. Non-invasive root characterization provides valuable information for environmental engineers.forest engineers, botanists, and plant scientists in general. Here, we evaluate acquisition parameters for GPR survey in the caatinga environment, an exclusive Brazilian biome (spanning eight states in the north-eastern region and part of one state in the South-eastern region). This biome presents high density of trees, making systematic GPR mapping a time-consuming task. In this project, we aim to establish the most practical survey design, including spatial sampling parameters, in order to optimise survey efficiency without compromising data quality. We explore data characteristics within a high-resolution 900 MHz GPR survey, 5 × 5 m in area. Root images show a promising correlation with biomass observed in trial excavations.
