This system has been designed to perform detailed pavement inspection. The IDS system is available as either a single double frequency antenna unit or as an array composed of 2 or 3 of these units. The two frequencies used are 600 MHz for characterising relatively deep layers and the choice of either 1600 or 2000 MHz for characterising asphalt or concrete pavements respectively.

The method chosen depends on your requirements in terms of layer detection performance and survey speed. A mechanical support is supplied to enable this special antenna to operate in contact with the ground for high accuracy surveys.

IDS has also developed the specific IDSGRED/IN/LAYERING software for this application.
