Figure 6 displays zoomed-in fragments of the radargrams extracted from a drone-based (a) and ground-based (b) GPR survey line. The X and Y axes represent the line distance along the Earth's surface and the measurement depth in meters, respectively. A discernible change between two geological layers is evident approximately 1 m below the surface, demarcated by a black dashed line. The upper soil exhibits a softer composition, characterized by the faster decay of the electromagnetic waves, resulting in a low-amplitude representation depicted with weak and blurred colors. Below this depth, a pronounced amplification reveals a denser layer. Several heterogeneous anomalies are observed within the upper soil layer, particularly around 0.3 m deep, indicating irregularities near the surface. These anomalies suggest that the terrain may not have been uniformly flat and might have undergone alterations for construction purposes, leading to localized soil 'pockets' near the surface, as delineated by a yellow dashed line. In the lower soil layer, distinct changes in the horizontal electromagnetic phases are noted at approximately 62-63 m of the profile length, accompanied by heightened amplification. This pattern suggests the presence of objects composed of stiffer materials, likely artificial structures such as archaeological walls made of limestone boulders, marked by a light blue dashed line. Note that the corresponding structural elements on both radargrams are emphasized by circles and dashed arrows. Figure 7 presents the mapped archaeological finding, distinguishing between ground-based GPR (small dots) and drone-based GPR (large dots). The color-coded scheme signifies different surveying groups corresponding to the direction of the GPR lines. For instance, the prominent red dots in the northern region represent drone-based GPR findings from east-west (EW) direction flights, while the significant green dots denote drone-based GPR  
Figure 6: Two radargram excerpts from a drone-based GPR survey (**a**) and ground-based GPR (**b**) lines showcase a distinct geological transition approximately 1 m below the surface. A black dashed line demarcates the boundary between two soil layers. The upper soil layer exhibits anomalies at around 0.3 m, suggesting irregular terrain (the yellow dashed lines). In comparison, the lower layer reveals changes in the electromagnetic phases at 62–64, indicative of potential artificial structures, possibly archaeological walls made of limestone boulders (the light blue dashed lines). The corresponding structural elements on both radargrams are emphasized by circles and dashed arrows. findings from north-south (NS) direction flights. The determined correspondence between the ground- and drone-based measurements implies that the recorded anomalies are consistent across both the ground and drone measurements and the NS and EW directions. Only those found that were recorded by at least three independent observations were considered important archaeological targets to enhance confidence in the archaeological significance of the subsurface features. Figure 8 shows the numerical mapping of the overlapping findings. The locations and shapes of the findings are irregular and randomly scattered across the site. Such a feature of the outcomes suggests the relation to the Early Bronze Age. This era was characterized by structures crafted from irregularly broken limestone and sandstone boulders intricately assembled into wall-like structures, as highlighted in the preceding introduction. The unique scattering pattern observed in this mapping aligns with the archaeological understanding of construction practices during the Early Bronze Age in the Hulata region.
