OKO-3 GPR with control unit

Ground Penetrating Radar OKO‐3 is a portable, lightweight and inexpensive system designed for non‐destructive environmental monitoring.

The OKO-3 GPR is a portable lightweight low-prices system designed for non-destructive environmental monitoring. The OKO-3 GPR includes control unit or control processing unit and antennas. All antennas are interchangeable and meet the needs of a broad range of applications.

GPR ANTENNAS

Antennas covers frequencies from 50 MHz for deep geological surveying to up to 2500 MHz for high‐resolution investigations. Using low‐frequency antennas, one can increase the depth of sounding.If high resolution scanning of the near surface section is required, though, it is advisable to use high‐frequency antennas. A combination of antennas with different frequencies yields best results.

SHIELDED ANTENNAS

For efficient work in conditions of existing air jamming (i.e. buildings, construction, power transmission lines, etc.), a set of antennas with shielded screen receivers and transmitters, protecting against the potentially harmful effect from the top semi‐sphere, are available.

DUAL‐FREQUENCY ANTENNAS

The integrated multi‐frequency GPR OKO‐2 is designed for automated location of objects at different depths, simultaneously and in real time. This GPR combines a control unit and two antennas with the different frequencies.

HORN ANTENNAS

Horn antennas are ideal for tasks associated with the high‐speed GPR surveying of elongated objects such as motorways and railways, which require ground lift‐off GPR location.

MULTIPLE LOW FREQUENCY ANTENNA: 15 MHZ, 25 MHZ, 35MHZ, 50MHZ, 100 MHZ

We can customize our low frequency antennas by customer's demand.
High frequency antennas (such as 1600MHz, 2600MHz, 2800MHz, 3000MHz) can be customized by customer's demand.
