ANTENNA ARRAYS

3d-Radar manufactures a wide range of antenna arrays suitable for different applications and operational requirements. Our current selection of arrays range from 9  transmitting and receiving antennas up to 41 pairs. The width of the antenna arrays ranges between 90 cm to 3.3 meters with frequency ranges from 200 MHz – 3 GHz.

DX-Series Multi-Channel Antenna Arrays

DX Series Antenna - Orientation of Elements Reduces Reflections in Captured Data

 

3d-Radar DX-Series antenna arrays allow scanning of up to 41 channels of GPR data over a continuous 200MHz to 3GHz frequency range. Near surface signal fidelity with the DX antenna is enhanced by orienting the sending and receiving antenna elements in opposite directions, minimizing antenna ringing while delivering high resolution imagery in collected GPR data.

The air-coupled antenna design offers clear impulse response with low ringing and high suppression of the direct wave from transmitter to receiver. Operated with the GeoScope ™ Mk IV step-frequency radar, the DX-Series antennas offer a unique capability of collecting 3-dimensional GPR data with dense line spacing, allowing full 3-dimensional data processing. The antenna has support for multi-offset recording and CMP, and has a built in GPS receiver.

Ideal for applications such as road/bridge deck inspection, utility mapping, archaeology, railway ballast inspection and military uses, the DX Series of antennas are available in 1.8, 2,1 2.4 and 3.3 meter widths.  Other antenna sizes are possible.  Contact 3d-Radar if your application requires a custom size.

VX-Series Multi-Channel Antenna Arrays

3d Radar VX1821 Antenna 1.8M wide, 21 channels

As with the DX series, 3d-Radar VX-Series antenna arrays allow scanning of up to 41 channels of GPR data over a continuous 200MHz to 3GHz frequency range and is compatible with the he GeoScope ™ Mk IV step-frequency radar.  The VX-Series antenna elements are oriented in the classic inverse V shape pioneered by 3d-Radar.  The VX-Series also has the capability of capturing CMP data and has a built in GPS receiver.

The VX Series has been used in utility mapping, archaeology, railway ballast inspection and military uses.  Available sizes are  .9, 1.2, 1.8, 2,1 2.4 and 3.3 meter widths.

  • Ground Penetrating Radar

    Ground Penetrating Radar (GPR) uses electromagnetic waves to map structures and objects below the ground surface. The radar waves from the antenna are reflected by interface layers inside the soil or by buried metal objects. In general GPR works well in sand/gravel and dry soil conditions with low soil conductivity but can not penetrate high conductivity materials such as clay and salt water.

  • 3d-Radar GPR

    3d-Radar uses antenna arrays for efficient data acquisition over large surfaces. This enables the user to create 3-dimensional images of the subsurface objects.

  • 3d-Radar Technology

    3d-Radar has pioneered the next generation GPR systems by introducing step-frequency technology in combination with unique antenna arrays.
