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.
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:
Integrated Radar Inspection System Version P (IRIS Version P)
The Portable Integrated Radar Inspection System - IRIS Version P is a self contained, low cost single antenna ground penetrating radar system designed for applications requiring field portability.
The IRIS-P includes a digital GPR control unit and real-time data acquistion/processing system with high intensity 12 Inch SVGA data display, touch screen control and internal hard disk storage.
This system was designed to operate with all of antennas and IRIS software. Standard features of the IRIS-P include DMI input for distance tagging, USB data ports for data download and connection of peripherials, GPS port and IRIS Software (Lite Version).
This system is ideal for man-portable applications and low speed pavement inspection.
Available is a complete and comprehensive line of air-coupled and groundcoupled antennas covering various resolution and depth ranges for pavement and bridge deck inspection applications, geotechnical and site surveys.
Air Coupled (Non-Contacting) Antennas
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.
Ground Coupled (Contacting) Antennas
The 2 nanosecond (500MHz) Model 501B, 2.5 nanosecond (400MHz) Model 401B and 3 nanosecond (300MHz) Model 301B are mid-frequency and low frequency contacting-type ground penetrating radar antennas with penetration depths of approximately 6 feet (2 meters) and 10 feet (3 meters), respectively.
These antennas are optimized for ground coupled operation and can be pulled manually and towed by vehicle. The Model 401B/501B can also be suspended from a vehicle in close proximity to the ground and when properly installed can be operated at speeds up to 35MPH (55km/hr). These antennas are a shielded, broadband dipole design that optimize bandwidth and minimize distortion resulting in superior subsurface detection capability.
Applications for these antennas include detection of deep pavement layers, subsurface pipe and utility detection, geotechnical applications including detection of buried drums and for general site surveys.
The 501B/401B/301B antennas are housed in a rugged plastic enclosure for maximum durability and incorporate removeable wheels for high mobility.
These antennas are compatible with all our GPR systems and software.
Hand Held (Contacting) Antennas
The Model 1001B and Model 2001B are shielded, hand-held contacting type antennas used for near range (shallow depth) inspections.
These antennas emit 1ns (1001B) and 0.75ns (2001B) monocycle pulses at high PRF. This family of antennas are optimized for near range and high resolution with maximum depth range of 1m (1001B) and 60cm (2001B).
The 1001B/2001B antennas are housed in a light weight aluminum enclosure. Typical applications include rebar location and rebar depth measurement, void location and thickness measurement.
For remote inspection an optional telescoping handle is available.
