Page 3: Description Of Device Operation
2. DESCRIPTION OF DEVICE OPERATION Device designation Search kit «OKO-2» is automated device and is designed for operative searching and detection dotted and extended metal and nonmetallic objects in various nonmetallic environments (ground, water, building designs and etc.) Device structure The device is the monoblock. -
Page 4: Arrangements Of Device Operation
Arrangements of device operation The SK operation is based on well-known radiolocation principals. The SK operation is based on ability of radio waves to be reflected from sections of environment boundaries with a different permittivity. Short signal pulses are applied for subsurface radiolocation. In order to form such pulses the excitation of the wideband transmitting antenna caused by the voltage swing is used. - Page 5 2.5.2 Operation device of component parts Receiving and transmitting antenna unit (BAPP) Receiving and transmitting antenna unit functionally consists of receiving, transmitting units and receiving and transmitting antenna unit with volumetric damping resonator. Receiving unit The receiving unit functionally consists of receiving antenna unit, the scan stroboscopic device, selection and storage device (SD) and the control unit.
- Page 6 The data from BUOI can be copied on a personal computer on interface Ethernet. The transferring order is described in the User’s manual. The further data processing can be made on a personal computer using Geascan32 software (see. The User s guide program Geoscan32). Autonomous power supply unit (BP) The autonomous power supply unit (BP) consists of ten Ni-Mh accumulators and the accumulator indicator of the category, which is control and indicate of the accumulator battery.

Page 9: The Device In Operating Position
The device in operating position. The device is to be in the hand in the position that are shown on the figure 3.2.1 It is necessary to chose the length of the shoulder belt that the major part of weight SK «Оkо-2» will be on the belt and at the same time the freedom of moving SK is provided (figure 3.2.2) BAPP is to be directed at the side of the scanning environment (rejection +_ 20 C from geometrical axis BAPP) and is to be moved in a parallel surface of cargo, close by or with a slight... -
Page 10: Preparation For Scanning
Preparation for scanning 1. Press the key on BP case for switching on the power supply of the device. At that time the Led indicator is to flash at the BP case and after several seconds of automatically SK testing and short- time message «Ready», on the BUOI screen is to display operation mode select menu of device (figure 3.3.1) current voltage of power supply unit and time. -
Page 11: Set Parameters Of Scanning
The first three half-periods of each line (on the figure 3.3.2 is allocate by a dotted frame in the image of wave form) as so called the signal of direct transmitting. The signal of direct transmitting is not to go to the scanning zone, it is to go directly – from transmitting antenna unit to the receiving and as a rule, it has the biggest amplitude in the current line. - Page 12 3. Press the functional key «2» («Epsilon*10», figure 3.4.2) to activate the options of environment dielectric permeability and with the following buttons “↑”and “↓” and to fix the required value of dielectric permeability. The value of dielectric permeability multiplied x10 is displayed on the screen for display convenience of a fractional part of dielectric permeability.

Page 13: The Operation Of Scanning
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). - Page 14 Local objects Figure 3.5.3 The examples of radogramm of detection objects 3. Press button «5» during recording for drawing label. Drawing the label accompany by sound signal. Program assign labels serial number. 4. Press «Esc» for save file and «Enter» for approval of saving (figure 3.5.4). File name Figure 3.5.4.

Page 15: Detection Of Movement
Detection of movement The mode intend for detecting the moving object in real time. Press the functional key «3» in main menu of BUOI («Det. move», figure 3.4.1) to activate the mode. Select item «Param det» (button «5», figure 3.6.1). Figure 3.6.1. - Page 16 The main condition for the moving objects detection is to fix the antenna unit on the wall through which the scanning of the adjoining room is made or to fix it on the floor for detection the objects that are below, on the previous floor-level. On the figure 3.6.2 there is a scheme detection of a moving person in the concrete tunnel.
- Page 17 For detection the moving objects through the wall it is necessary to fix the antenna unit on the wall, do not try to keep the unit by hands, it can make the detection of the moving objects complicated. On the Figure 3.6.4 there is the detection radogramm of the moving animal (dog). The scanning was made through the brick wall of the adjoining room, the thickness is 40 cm.

Page 18: General Recommendations
General recommendations It is necessary to perform the following recommendations during search work: 1. The device should move along the trajectory planned by operator closely or with distance (up to 0,1 m) from the surface of the scanning environment. 2. The speed of the antenna block moving should be no more than 1 km/s while you are scanning the complex surfaces on the relief. -
