Description

Technical Field

[0001] The utility model relates to the technical field of ground penetrating radars, in particular to a protective ground penetrating radar. Background Art

[0002] Ground penetrating radar is a non-destructive testing technology used to detect underground objects, terrain and structures. It obtains information about underground objects by sending radar signals underground and receiving echoes, and then uses this information to generate images or models of underground structures. This technology is widely used in geological exploration, archaeology, construction engineering, mineral exploration, safety detection and other fields. The working principle of ground penetrating radar is based on the propagation and reflection characteristics of radar waves in different materials and structures. When the radar wave encounters an underground object, it will be partially reflected back and received by the receiver. By analyzing the received signal, the location, shape and properties of the underground object can be understood. In general, ground penetrating radar is a non-invasive, efficient and accurate underground detection technology, which provides an important means for the detection and analysis of underground structures.

[0003] The existing ground penetrating radar needs to be manually pushed to move lightning for detection. There are obstacles during the movement. When the ground penetrating radar collides with these obstacles, the impact force is large and it is easy to cause damage. The service life of the ground penetrating radar is short. Therefore, we propose a protective ground penetrating radar to solve the above problems. Utility Model Content
