Considering the high-resolution power of the ground penetrating radar method, as well as the high speed and ease of acquisition, it can be said that this method is useful in investigating and detecting shallow subsurface targets similar to subsurface holes, canals and other targets that have a different dielectric constant from the surrounding environment. It is an acceptable method. In addition to the effect of the frequency of the waves sent from the GPR antenna, other factors such as soil moisture, the amount of fine-grained clay materials or the fineness of the sediments in general, reduce the depth of investigation or penetration of GPR waves. This problem is mainly caused by the higher electrical conductivity due to the presence of moisture or fine-grained sediment particles compared to coarse-grained sediments. In this study, a ground penetrating radar device with 80 MHz antenna was used and seven profiles with a total length of 662 meters were taken in order to investigate the intersection of Kargar Street in Tehran. The radargrams have been processed and the anomalies related to the meetings have been identified on them. These anomalies are discussed in the next step on the positioning satellite images and on the obtained results. According to the estimated results, there is a good agreement between the anomalies detected in the parallel profiles, which can be a proof of the acceptable identification of possible anomalies in the study area.
