Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to a portable multi-modal perspective radar system and a control method thereof. Background Art

[0002] Ground penetrating radar technology is a detection technology that uses high-frequency electromagnetic waves to obtain the distribution law of underground media. Common time-domain ground penetrating radar can image and locate underground targets based on the reflection and scattering of broadband electromagnetic wave pulses at discontinuities in underground media, and perform high-resolution detection of targets several centimeters to tens of meters underground. This technology plays an extremely important and extensive role in military investigations, mineral geological exploration, engineering quality inspection, archaeology, search and rescue, etc. Among them, portable ground penetrating radar is used for the detection of shallow ground or wall cavities, water leakage, cracks and other diseases, as well as the assistance in locating the internal pipelines and structural distribution of buildings due to its small size and high precision. It helps locate and prevent disasters and assists in construction.

[0003] Like common hand-pushed and vehicle-mounted ground-penetrating radars, portable ground-penetrating radars are mainly composed of four parts: receiver, narrow pulse signal source, transceiver antenna, and host computer. When in use, the data collection on site is completed by receiving, sampling, and imaging the radar echo, and then algorithm processing and disease analysis and location are performed through special data processing software. However, since the means of automatic processing and analysis of ground-penetrating radar data are not yet mature, most disease detection is still highly dependent on the experience of engineers, resulting in low radar data processing efficiency, subjectivity and instability in accuracy.
