The operation of scanning
1.
Set the antenna power supply unit on the surface which is to scan and press the functional button
«2» («Record», figure 3.5.1) for the record of a profile.
Figure 3.5.1. Measurements mode menu
2.
Smoothly move the antenna power supply unit on the planned trajectory. The search of the deep
objects is possible to make at the mode, that is similar to the operation with metal detectors and mine
detectors (figure 3.5.2). Antenna unit is possible to take of from a ground surface on a distance 5-10
sm. It doest influence on the detection characteristics. The device in equal intervals will radiate
impulses and accept signals from the moving antenna unit of the device, that are reflected from
inhomogeneities of the scanning environment. The wave picture of the profile (radogramma) will be
displayed on the BUOI screen while the device will be moving. The reflection of point objects is
displayed on the radogramma as hyperbola (a vertex of hyperbole is to correspond to the nearest point
of objects of the antenna unit), reflection from the objects and layers are represented in tended
horizontal lines (figure 3.5.3).
