Table 2 Summary of electromagnetic wave detection and location technologies
From: Current Trends and Perspectives of Detection and Location for Buried Non-Metallic Pipelines
Methods | Detection and location conditions | Accuracy | Interference | Strengths | Weaknesses |
|---|---|---|---|---|---|
GPR[16] | Big difference of electrical characteristic | High | Small | High efficiency, anti-interference, easy to operation | Limitations by low diameter and complex environment |
RFID[53] | Buried tag near the buried pipeline | High | Small | Accurate location, easy to operation | Short life of the electronic tag |
