Ground Penetrating Radar System


Integrated Radar Inspection System (IRIS)

The Integrated Radar Inspection System (IRIS) is an automated radar based system for non-destructive inspection of highway and bridge deck pavement solving the problem of radar data interpretation and ease of use.

The IRIS consists of ground penetrating radar technology, ACPRO data acquisition/processing system, and IRIS Software for Windows, all integrated into a highly automated, turn-key inspection system that requires little knowledge of radar signal interpretation to operate effectively.

Ground Penetrating Radar System

Designed for use at highway speeds of 60 MPH (100KM/H) the IRIS �sees� through asphalt and concrete pavement, and bridge deck structures, automatically acquiring and storing digitized radar data on hard disk for subsequent processing and display.

Signal processing is automatic requiring limited user input and provides hardcopy data output mappings of bridge deck deterioration and pavement thickness profiles.

The IRIS utilizes antennas and can be installed with up to four antennas in an array for maximum pavement inspection coverage. A complete IRIS system consists of the following components:

  • Model PS-24 Ground Penetrating radar, installed with up to four Antennas

  • ACPRO Model PS-AP3 Data Acquisition and Processing System

  • IRIS Software for Windows

  • Full touchscreen interface for GPR control

  • Uses include the non-destructive evaluation and testing of bridge deck and highway pavement, detection of delamination in bridge deck concrete, pavement layer thickness measurement, pavement moisture accumulation and voids beneath rigid highway pavement.

  • GPS Compatible

    These antennas exhibits ultra wide band performance and very low VSWR, with minimal distortion throughout the bandwidth of the applied signal.

    Its narrow beamwidth and high directivity minimize interfering clutter sources.

    These antennas are optimized for applied signals within the range the range of 0.75 ns to 2.5 ns and are available in both monostatic and bistatic configurations.

    Transceiver units are interchangeable depending on desired pulse width.

    The air-coupled antennas are constructed of low dielectric material with a hard plastic outer covering for durability and high speed (60MPH/100km/hr) operation. When ordering specify antenna and transceiver pulse width.
