DX-Series Multi-Channel Air Launched Antenna Arrays



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 transmitting and receiving antenna elements in opposite directions, minimizing antenna ringing while delivering high resolution imagery.

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 has a built in GPS receiver.

Ideal for applications such as high speed road/bridge deck inspection, network level utility mapping, 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.

  • 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.
