Typical Uses

The SIR 30 is typically used for:

Road structure assessment
Utility designation
Bridge deck inspection
Rail bed inspection

Rugged Design

The SIR 30 is built with an aluminum exterior and rubber bumpers, and sized for vehicle rack mounts. For operation in harsh environments, GSSI created the SIR 30E, a modified version of our popular SIR 30. The SIR 30E can collect up to two channels of data.

Data Examples

SIR 30 4 Channel Data

Data illustrates multiple utilities at varying depth. data was collected as a 4 channel 400 MHz antenna array system with a custom made (user provided) cart configuration.

SIR 30 2 Channel Data

Using a 2 GHz horn antenna, the top channel records asphalt layer thickness. The bottom channel shows sub-base layer information, including a shallow utility, that was collected with a 400 MHz antenna

Mining: Determine Mine Safety

Mining professionals use ground penetrating radar to accurately locate underground structures before drilling, blasting or carrying face operations. GPR is instrumental in helping to identify overhead separations in order to prevent ceiling collapses. In deep mine applications, GPR is invaluable for identifying geologic features that may be potential areas for rock bursts, such as fractures, shear zones and faults.

This data illustrates a GPR scan of the roof in a salt mine and shows the variable thickness of salt in a roof structure. This was collected with a SIR 30E and a 400 MHz antenna.
