QL-GPR 400 Ground Penetrating Radar System

The QL-GPR 400 is a field-ready 400 MHz ground penetrating radar system with a shielded antenna, integrated GPS, real-time 2D imaging, 3D post-processing, a rugged IP66 field laptop, and more than eight hours of battery operation. It supports utility locating, geotechnical surveys, transportation inspection, forensic work, and buried-object detection.

OVERVIEW

Description

The QL-GPR 400 is a 400 MHz ground penetrating radar system for accurate subsurface surveys. It combines a shielded radar antenna, integrated GPS, a rugged field laptop, professional software, and a three-wheel survey cart.

The system displays real-time 2D radar data during field surveys. In addition, operators can process the collected data to create 3D subsurface views. Therefore, survey teams can check data quality in the field and complete detailed analysis after the survey.

The QL-GPR 400 supports utility locating, geotechnical surveys, transportation inspection, forensic work, and buried-object detection. Its weather-resistant design also supports reliable operation across paved surfaces, rough ground, and wooded areas.

High-Resolution Subsurface Imaging

The shielded antenna uses a center frequency of 400 MHz. It provides clear subsurface imaging while reducing surface interference and external radio-frequency noise.

Operators can use the system to locate and inspect:

  • Underground utilities
  • Pipes and cables
  • Buried structures
  • Subsurface voids
  • Pavement features
  • Geotechnical layers
  • Archaeological targets
  • Other buried objects

Moreover, the system displays radar profiles as operators move across the survey area. This real-time view helps users identify targets and confirm data quality before leaving the site.

GPS Positioning and Survey Modes

The integrated GPS records coordinates for radar profiles and detected targets. As a result, operators can create georeferenced survey maps for engineering, analysis, and reporting.

The QL-GPR 400 supports four survey modes:

  • Continuous survey mode
  • Distance-based survey mode
  • Point-based survey mode
  • GPS-based survey mode

These modes help teams adapt the survey process to different surfaces, site layouts, and project goals.

Data Processing and Reporting

The professional software suite supports both field data collection and post-processing. Operators can review, improve, interpret, and export survey results from one platform.

Software functions include:

  • Real-time 2D data acquisition
  • On-the-fly 2D visualization
  • Post-processing 3D visualization
  • Signal filtering
  • Gain adjustment
  • Target annotation
  • Color and grayscale display
  • Data storage and retrieval
  • Data reprocessing
  • Data export
  • Report generation

In addition, 3D processing helps operators study complex utility networks and buried structures after data collection.

Rugged Field Operation

The system includes a rugged laptop with a display size of 10.4 inches or larger. The computer comes with the operating system and GPR software already installed.

The field computer provides:

  • USB connectivity
  • Micro-USB connectivity
  • HDMI output
  • Ethernet connectivity
  • Wireless connectivity
  • Pre-installed GPR software
  • IP66 weather-resistant protection

The system operates from −22°F to +158°F (−30°C to +70°C). Therefore, teams can use it in a wide range of field conditions.

Long Battery Runtime and Easy Mobility

Two rechargeable batteries and a compatible charger come with the system. Together, they provide more than eight hours of continuous operation.

The professional three-wheel survey cart keeps the antenna stable during data collection. It also supports use on:

  • Paved surfaces
  • Rough terrain
  • Wooded terrain
  • General outdoor survey areas

As a result, operators can move the system smoothly while maintaining a steady antenna position.
