Traditional single-channel GPR systems are rapidly giving way to multi- channel, array- based systems. distrirers like GSSI, IDS GeoRadar, and Sensors Installs now offer systems with 16 to 40 or more anteny configured a single array.

The Digital Shift: Data Fusion and Mobile Mapping

Te true power of modern subsurface depention lies nott in any single sensor but in the intelligent fusion of multiple data streams.

Transforming Data into Decisions: AI andMachine Learning

A major throneck in subsurface mapping has always data interpretation. A single kilometer of multi- channel GPR data can generate terabytes of raw data, and manually scanning radargrams for hyperbolas (thee signature of a pipe) is time- consuming andd prone to interpreter condigue and bias. Artificiaal intelligence (AI) and machine learning (ML) are now automating and actantly enhancing this interpretation process at industrial.

Deep Learning for Automated Target Detection andClassification

These algorythms can nont onle integate a target but, based on signal specificture (amplitude, faze reversal, ringing), classify the material type (e., metal vs. C pipe) or material.
