Their main product, Pipe Hawk, uses a 500 MHz antenna. Its software is aimed at the detection of pipes and cables, with the possibility of automatically detecting such long objects by analysing multiple parallel scans after migration processing. Their other product is a highway inspection system, which uses multiple higher frequencies antennas in parallel. Finally they have developed during the Gulf War a portable mine detection prototype system, whose development has been stopped by lack of interest from the military.
Their product, the SPRScan, uses a 500 MHz antenna (antenna with higher frequencies could be available). The software running on a compact 486 industrial PC displays scrolling vertical slices of the soil in real time. There are multiple possibilities of gain adjustment and filtering, but no data migration. The "3D" version of the software is able to generate horizontal slices from the data of multiple parallel scans. That system has been chosen by DeTeC for the first part of our project using a prototype 1GHz antenna.
Complete systems from 15 MHz to 2.5 GHz.
Manufacturer of Stepped-FM GPR.
They produce and sell GPR equipment since 1994. All the system they have designed are aimed at a particular field of activity: e.g. the RIS/S is dedicated to pipe detection and location within the first 1.5-2 meters of the soil, the /MF to pipe location and soil recognition within 3 meters of depth, and the GP0 is a versatile and general purpose equipment.
KSD-21 Ground Penetrating Radar:
A wide variety of antennas are available ranging from 50 MHz to 2 GHz,
enabling the optimum radar frequency to be selected. Every radar can be
connected to the KSD-12A Radar Controller without any additional
hardware. The KSD-21 is controlled by a PC (DOS/V machine).
The standard software (KSF-01) implemented on the KSD-21 system enables
on-the-spot selection of optimum survey conditions for the given
objective. Data processing necessary for displaying the survey results
can be performed as well; an optional software package for differential
processing, spatial filtering and averaging is also available;
customized signal processing software can be added, too.
Manufacturer of ground penetrating radar equipment for both surface and borehole applications in geophysical, geotechnical and civil engineering fields
They are manufacturing pulse GPR Zond-12c (25 MHz-2GHz) and
Python-02
(24-190 MHz), rather popular in Russia.

Radiophysics Department
(http://radio.stu.neva.ru/index.htm)
of the Radiophysical Science and Engineering Faculty (St. Petersburg
State Technical University), featuring also Short-Range High-Resolution
FMCW Subsurface Radars (0.5-1, 1-2 and 2-4 GHz).
Custom designed antennas from 10 to 3000 MHz.
Road Radar Ltd is both a system manufacturer and a data acquisition service provider. Their radar has been developed specifically for subsurface inspection of roads and bridge decks. The system, mounted in a van (max. survey speed : 100 Km/h), employs a hybrid antenna system consisting of a surface coupled antenna (center frequency : 1GHz) and an air-launched antenna (3 GHz). A signal processing environment allow to combine the data from both radars for automated data interpretation (continuous profile of multiple pavement layer thickness, location of voids, identification of cracks, etc).
They have an interesting technology ("microwave retina") to produce a complete vertical slice without moving the antenna, using an array of modulated dipoles. They use synthetic pulse technology. They have no standard products, but instead develop specific solutions targeted at each application. Main applications are production monitoring, non-destructive testing and antenna field measurement. They have worked with frequencies ranging from 500MHz to 13GHz depending on the application.

The pulseEKKO GPR systems are "professional" systems that give users a
wide variety of system configuration options for many applications and
mapping in complex regimes. The pulseEKKO software displays GPR data
on-screen in real-time, and allows users to process and manipulate
their
GPR data post-survey. These systems require user input for set up.
Antenna frequencies range from 12.5 MHz to 1.2 GHz.
The Noggin systems are ideal for beginners or those requiring a quick map of an area. These systems include all GPR electronics needed in a simple rugged package. The Noggin GPR systems are compact, lightweight, and weather-proof. These systems come with SpiView Software which displays the subsurface information on screen as it's being collected and offers output to pcx file format or printer. Noggin Systems available: Noggin 250, Noggin 500.
The Noggin Smart Cart System makes Noggin surveys even easier. The cart comes complete with a digital video logger (DVL) with integrated CartView Software, a battery, and odometer wheel, a sturdy frame, and has four wheels for stability and easy manouvering. The cart displays subsurface information in real-time on the DVL screen, and allows users to accurately locate areas of interest. Once the user passes over an area of interest, they can then stop and reverse with the cart, and the DVL cursor will move along the screen indicating the postion of the operator on the data. The user can then mark the area and continue surveying. The user does not need to remember where he left off, because the smart cart will not collect data again until it reaches the position the user previously stopped and reversed at. The Noggin Smart Cart is available as a complete GPR unit with the option of the Noggin 250 or Noggin 500 included. The Cart is also available as an enhancement item to existing Noggin owners.
Their product, the Imra system, is a very compact lightweight
handheld
GPR. The system is aimed at short range measurements, typical described
applications being ice thickness measurement and rot detection in
telephone
line poles. The standard antenna has a 1 GHz center frequency and
optional
800 MHz and 1.5 GHz antennas are available.
