Ground Penetrating Radar (GPR) systems - GSSI
SIR-30 system by GSSI

SIR-30
  • Overview
  • Benefits
  • Specifications

The SIR-30 is the next generation high-performance multi-channel radar control unit. This system can collect up to eight channels of data simultaneously with uncompromised performance.

The SIR-30 offers advanced filters and display capabilities for real-time processing, including migration, surface positioning, signal floor tracking and adaptive background removal.

Ideal for high-speed data collection of: measuring pavement layer thickness, detection of cavities, airport runway assessment, detection of fouled/clean ballast and utility detection.

Typical Uses of the SIR-30 include:

  • Road structure assessment
  • Utility designation
  • Bridge deck assessment
  • Rail bed inspection
