Ground-penetrating radar (GPR) plays a crucial role in archaeological exploration by providing a non-invasive understanding of subsurface characteristics [1; 2; 3; 4; 5; 6]. Within archaeological research, site preservation, and cultural heritage conservation efforts, the prevalence of the GPR methodology has steadily increased over time. This rise can be attributed to several key factors: (a) their efficiency, utility, and cost-effectiveness render them invaluable tools for archaeological investigation and cultural heritage preservation, thereby minimizing excavation efforts and decreasing human energy expenditure; (b) they provide non-invasive and non-destructive approaches to site exploration, ensuring the conservation of investigated areas; (c) they allow for precise determination of the location of buried archaeological artifacts; and (d) by integrating with other disciplines, they facilitate the reconstruction of a site's history [6; 7; 8; 9; 10]. The utilization of a comprehensive methodology, integrating geophysical techniques (including ground-based GPR, remote aerial, and satellite imagery) along with archaeological inquiries at the Bronze Age site of Sissi on Crete, was detailed in [11]. The study revealed that conducting thorough geophysical surveys offers a more comprehensive understanding of unexcavated or partially excavated layouts. [PERSON] et al. [12] used GPR to detect underground voids beneath the St. Sebastiano church in Catania (Sicily). They showed that GPR enabled their successful revealing. [PERSON] et al. [10] demonstrated that GPRallowed the identification of buried structures' positions, depths, and dimensions. It further facilitated the assessment of the foundation geometry and its structural integrity. The comprehensive field campaign confirmed the effectiveness of applying GPR with 200 and 400 MHz antennae [13]. It was shown that the anomalies observed by GPR corresponded to fire-hearth structures, wooden artifacts, tree roots, and rocky bodies, such as speleothems, boulders, and bedrock. Observations indicate that the persistent application of conventional ground-penetrating radar (GPR) acquisition and processing methodologies is imperative for investigating sub-terranean cultural artifacts. Nevertheless, there is a strong emphasis on adopting innovative approaches for data acquisition, post-processing, and interpretation [1]. One advantage is using a multi-antenna array for large study areas and a pseudo-3D methodology based on collecting several parallel lines [3, 4, 8]. Several successful applications of such methods were demonstrated in [3]. Another way to improve the quality of GPR studies is by integrating them with other geophysical techniques. For example, the applicability of magnetic, ERT, and electromagnetic induction methods was highly prospective in the integration with GPR [2]. The preliminary results, which showed the existence of Early Bronze Age (c. 2600-2400 BC) buildings and pottery in the Syrian Middle-Euphrates valley [14], motivated the application of GPR, which revealed the existence of unknown buildings on the streets and the enclosure wall of the city. Another example showcasing the successful use of GPR was highlighted in [15], which revealed traces of ancient human activity during the Stone and Bronze Age periods at the Asaviec settlement site in Northern Belarus. The procedures for the application of the magnetic and resistivity methods were reviewed in detail in [16, 17]. It was noted that three-dimensional and virtual-reality models have become common, and the integration of the results of several methods is quite desirable [18]. An example of the successful combination of GPR with magnetic mapping and magnetic susceptibility measurements was presented in [19], which has proven effective in identifying concealed archaeological structures.
