In 2012-2014 ESTRA has developed UWB radar technologies: transceivers, antennas, amplifiers, signal processing software. In 2013 we developed multifunctional GPR device

• PicoR. Now we continue to test this device in

different environments and improve software. During last 2 years we have sold over 100 GPR devices PicoR in Russia, Sweden, France, Iran

Who we are

2

• ice, snow, road pavement thickness

measurement and survey

• searching for objects in the ground
• detection of people behind walls

Our PicoR GPR can perform

3 All of this GPR devices:

• have almost the same hardware but different software
• are high frequency GPR that is they have high resolution

but rather low operating depth

• are much more cheap than competing GPR and designed for

mass application

Purpose of the product

11

The device is a high-resolution GPR adapted to be used to determine the thickness of asphalt concrete pavement and pavement condition, namely: 1) Thickness of the asphalt-concrete pavement in the real time automatically (for road segments that satisfy the model described in the software - up to 60-80% of the length of the road) or manually using post- processing (for other sites). 2) Quality of the pavement. 3) Substrate type (concrete - breakstone - reinforced concrete). 4) Areas of mismatch of pavement. Also the device can be used as traditional GPR for searching objects under the ground – pipes, buried objects. Best of all, these objects can be found due to different layers of the ground during excavation which are well defined by radar

Advantages

13

• High performance allowing to work at the speed of 40-60 km/h
• Automatic processing of the signal, the selection of the layer and the

automatic calculation of the layer thicknesses

• Possibility of convenient manual correction of border lines in unstable
• peration of the automatic algorithm in “difficult” places of road
• Miniature size of the device and light weight make it easy to transport

by one person in a standard laptop bag (without fastening a car)

• When mounted on the car it almost does not increase the size
• Low cost is less than the cost of the closest analogues 3-4 times.

By retail the price of the device depending of the configuration is 4500-6500 USD It’s optimal to use this device with low frequency GPR (around 500 MHz) which let you see all the layers of pavement (depth up to 2-3 m) but with a lower resolution

Through-Wall Imaging device

14

is designed to detect people over the walls, under the rubble and any

• ptically opaque barriers (walls and floors of buildings, including concrete

slabs, unlit rooms, piles of building materials, damaged structures and rock avalanches, etc.), both moving and stationary (by wiggling and breathing). The device allows the operator to see people in the room “through walls” to determine the distance to them in real time, also the operator can see whether they are moving or not. For special services, police, rescuers

15

Device testing on the landfill of Ministry of Emergency Situations. We can find a person under several concrete slabs at 1.5-2 m

• ver his moving and breathing

Using the device

Variant of fixing the tablet PC

16

We see moving person from 0.5 to 4 m in the room behind the brick wall of 30 cm thickness
