Ground penetrating radar is a geophysical tool for the underground environment inspection. GPR emits a broadband radio frequency signal and records the reflection of the signal from different objects of the soil ground.
The geo-radar consists of three basic elements :

Transmitter: the block of the probing impulses formation with the transferring antenna.

Receiver: the block of reflected signals registration with the reception antenna.

• Control and indication unit

During the work of a geo-radar, the transmitter (the block of the probing impulses formation) radiates in depth a short impulse -an electromagnetic signal-. This signal extends in the soil ground and in air where experiences various wave processes. The signal, which has reached the ground surface to the reception antenna is received, amplified, digitized and registered in memory of the geo-radar by the registration block.
The propagation velocity of the wave, dielectric permeability of the medium, specific, characterizes propagation of electromagnetic waves in various media

Our Devices:

GPR LOZA is the device used by our company, it has two types LOZA-V and LOZA-N.
GPR “LOZA” depends on generating high electromagnetic power from a discharging capacitor during very small time interval (Nano seconds), the antennas create the signals and transmit them. That differs from other European GPR and some Russian types which uses continuous transmission method.

1.LOZA-V: high frequency GPR.

2. LOZA-N: Low Frequency GPR.

LOZA-V used for high resolution, and LOZA-N is used for great depths.
