AI Technical Summary

Technical Problem

Existing technologies cannot effectively and non-destructively identify and locate Cynomorium songaricum in desert sandy soil, resulting in low detection efficiency, low accuracy, and damage to plants.

Method used

A ground-penetrating radar-based device and method are used to transmit electromagnetic waves using a 400 MHz radar antenna. Combined with GPS positioning and a ranging wheel, the target of *Suoyang* is identified by analyzing the difference in dielectric constant, generating radar images and outputting geographic coordinates.

Benefits of technology

It enables rapid and accurate detection of Cynomorium songaricum at depths of 0.2 m to 1.5 m underground, improving identification accuracy, avoiding physical damage, and is suitable for complex terrain, thus improving detection efficiency.

Abstract

This invention discloses a ground-penetrating radar (GPR)-based device and method for detecting and identifying Cynomorium songaricum under sand, belonging to the field of traditional Chinese medicine resource detection technology. The device includes: a GPR for transmitting electromagnetic waves into the sand and receiving reflected signals from the underground medium; a control center module, communicatively connected to the GPR, for controlling the signal transmission and reception of the GPR, and collecting GPR echo data and corresponding spatial location information; a positioning and ranging module, communicatively connected to the control center module, for recording the spatial coordinates and travel distance of the detection and identification device in real time; and an offline data analysis module, communicatively connected to the control center module, for receiving and processing the GPR echo data and spatial location information, generating a radar image of the underground medium, and identifying the Cynomorium songaricum target in the radar image. This invention enables rapid, accurate, and non-destructive positioning and identification of Cynomorium songaricum under sand.
