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.

VX-Series Multi-Channel Antenna Arrays

3d-Radar VX-Series antenna arrays allow scanning of up to 41 channels of GPR data over a continuous 200MHz to 3GHz frequency range. 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 VX-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 VX Series of antennas are available in .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.
