Detection GPR Imagery

The GPR Image shows a typical detection.
Anomalies are overlaid in red to facilitate recognition.

Deep and Shallow Anomaly Imagery

Small, shallow buried object detected.
Detection Sweep‑Speed Effect
The Operator can sweep the detector slowly or quickly, up to approximately 1 metre (3‑feet) per second.
Sweeping the Sensor Head quickly will compress the visual image on the display. Sweeping the Sensor
Head slowly will elongate the visual representation of the anomaly.
Large target detection with a fast sweep-speed. The imagery
becomes compressed across the time period.

Noisy GPR Imagery

The GPR Image is noisy, making it difficult to identify true
target signals among the erratic detections. Note the
straight horizontal bands in the image, including above
the ground surface. Skyshot procedure is required.
Deep buried object detected.
The same target detected with a slow sweep-speed. The
imagery becomes elongated across the time period.
