Overview

Randomized trial compares accuracy of frequency-domain data fusion methods for underground facility detection, suggesting enhanced reliability.

Key Points

  • This study aims to improve the detection accuracy of non-metallic underground facilities using advanced GPR techniques.
  • Compared performance of hyperstacking GPR and real-time sampling GPR for facility detection.
  • Evaluated data fusion in the frequency domain using different frequency ranges.
  • Assessed mean absolute error and signal-to-noise ratio across different GPR configurations.
  • Hyperstacking GPR achieved a 62% reduction in error compared to real-time sampling GPR.
  • Frequency fusion of 350MHz HS GPR and 800MHz RTS GPR resulted in an average absolute error of 0.022m, improving accuracy by approximately 8.3%.
  • Fusion with lower frequency channels decreased accuracy, highlighting the importance of data quality in performance.
