Ground-penetrating radar (GPR) was used to monitor 12 pig burials in Florida, each of which contained a large pig cadaver. Six of the cadavers were buried in sand at a depth of 0.50-0.60 m, and the other six were buried at a depth of 1.00-1.10 m and were in contact with the upper surface of a clay horizon. Control excavations with no pig internment were also constructed as blank graves and monitored with GPR. The burials were monitored with GPR for durations of either 12-13 or 21-21.5 months when they were then excavated to correlate the decomposition state of the cadaver with the GPR imagery. Overall, cadavers in sand were easily detected for the duration of this study at 21.5 months, even when completely skeletonized. Conversely, in clay it became increasingly difficult to image the pig cadavers over the first year of burial, even when they still retained extensive soft tissue structures.
探地雷达（GPR）被用于监测佛罗里达州的12处猪的埋葬情况，每处埋葬都包含一头大型猪的尸体。其中六具尸体被埋在深度为0.50 - 0.60米的沙子中，另外六具被埋在深度为1.00 - 1.10米处，并与一层粘土层的上表面接触。没有猪尸体埋葬的对照挖掘也被建造为空白坟墓并用探地雷达进行监测。这些埋葬点用探地雷达监测了12 - 13个月或21 - 21.5个月，之后进行挖掘，以将尸体的分解状态与探地雷达图像相关联。总体而言，在本研究为期21.5个月的时间里，沙子中的尸体很容易被探测到，即使完全变成骨架。相反，在粘土中，在埋葬的第一年里，对猪尸体进行成像变得越来越困难，即使它们仍保留着大量的软组织结构。
