Ground penetrating radio is a geophysical technique that detects patterns in the ground. It uses high frequency pulsed electromagnetic waves to penetrate ground and return signals to the surface. GPR can reach a depth of approximately 0.5 m depending on the type of soil or rocks.
Ground-penetrating Radar can also help locate buried artifacts or objects. It can also help locate old mine shafts and septic pits. It can also be used for searching for missing items at crime scenes. It can be done in one person, unlike other types of surveying. This requires a lot expertise and experience.
Ground penetrating radio has been used for the detection of unmarked graves in cemeteries since its inception, in the 1990s. Some of the most famous examples are the remains and remains of children who died in a Kamloops, B.C. residential school. and the remains homicide victims.

Kisha Supernant, University of Alberta, has used technology to assist Indigenous communities in finding buried artifacts or human remains. At least 35 graves were found at Muskowekwan First Nation in Saskatchewan. She stated that she expected to finish her report by the end this month.
A ground-penetrating radar can be used to scan a grave for any "turned" soils or other surface disturbances. This information can be useful in future projects. It can't always provide you with the most direct information. There are other factors to consider when interpreting the results.
Surveyors are not allowed to ignore any nearby objects that could interfere with the signal when they're conducting a survey. You should avoid including any land sales or transfers in your radargram if you're scanning a cemetery.
Surveying a grave can be difficult, as you can see. The surveyor must not only locate the grave but also explain to the community that they discovered a grave shaft. The problem with a burial is the difficulty in distinguishing between the bones of the deceased from other materials.

Prehistoric animals' skeletal remains were often covered in sediment, making it difficult to identify. Geophysical methods have been successful in detecting disturbed soil within graves.
Although these technologies are not yet able to detect bone presence, they suggest that this material is a low-loss target for GPR. Modern animal bone has electrical properties that make it a desirable target.
Despite its limitations, ground-penetrating radar can be an effective method to locate a gravesite, particularly if it is a clandestine grave. In addition, it can detect voids, casket lowering apparatuses, and metal lumps. The burial depth depends on the site features and materials.
