Purpose Radar Detector (RD-400) is portable radio detection system designed to locate survivors buried under rubble or debris by either movement or breathing. 3. Set of RD-400 Radar-Detector The RD-400 set consists of: 1. RD-400 Radar Detector 2. BP-9-12 power supply unit 3. ZU-9 charger 4. Rugged tablet PC 5. Charger for tablet PC 6. Radio modem unit 7. Documentation (Operation Manual, Certificate) 8. GeoScan32 software, base version (installation CD). Outside view of RD-400 radar detection device is shown in Fig. 3.1. 2 Tablet PC B-9/12 power supply unit Set of chargers Wi-Fi unit Radio detection device Figure 3.1. RD-400 Radar-Detector 4. Preparation and sounding The operation and selection of sounding parameters of the device is controlled by the software installed in tablet PC included in the device set. Transition of control commands, data exchange between RD-400 and tablet PC is carried out via WI-Fi channel, which automatically switches on at RD-400 power up, and in the tablet PC – after the program start-up. Operation procedure of RD-400 radio detection device: 1. Switch on power supply by pressing the button of BP-9-12 power supply unit to “On” position. 2. Place the radio detection device on the surface of a medium to be analyzed. Emission of sounding radio signals is pointed toward the case bottom (the side opposite to cover of the case) having protective rubber legs. 3. Switch on tablet PC. Select tag finger. on the PC Desktop and tap on it twice with your 3 Tag of RD-400 program Figure 4.1. Icon of RD-400 control program on the PC Desktop 4. Window shown in Figure 4.2 will display on screen of tablet PC after the program start. The “Search of AB” caption appearing at first moment means the process of establishment of connection between RD-400 and tablet PC; the caption goes out when connection is established.

Further, the radio detector device switches over to data analysis mode (Figure 4.3). Zone of the reflected signal spectrum presentation goes into the analysis time indication mode , and the filling time of this zone corresponds to the time of analysis. There is an additional caption, which shows up in the same zone: “Please wait. Data under acquisition» Figure 4.3. Main window of radio detector device program After data analysis, in case of the object detection by its breathing the program window will be as shown in Figure 4.4. Cryptogram with the image of a man appears on the screen supplied with distance to object detected by its breathing. Additionally the spectrum of reflected signal from the object detected by its breathing and position of hardware threshold of the device (red line) starts displaying in the right side of the main window. The form of spectrum of reflected signal extends the operator’s capabilities in forecasting and estimating the situation on the likely presence of breathing object under the obstruction. Appearance of a pronounced peak in the spectrum refers to the object detection by its breathing. Moving the line that corresponds to the hardware threshold using “+” and “-” buttons allows to set up most comfortably the size of spectrum of reflected signal. 5 Spectrum of reflected signal from the breathing object Location of hardware threshold Indication of object detection by its breathing Figure 4.4. View of window of radio detection device program in case of living object detection by its breathing Apart from the view seen in Figure 4.4, the RD-400 program displays the results of sounding as shown in Figure 4.5, which is switched over by “Change view” button (Figure 4.2, item 11). Radargram is displayed in the left part of the screen. In case of the object detection by its breathing, a blue line located relative to the scale of distances according to the distance from the radio detection device to the detected object is drawn on the radargram. Indication of object detection by its breathing Figure 4.5. View of window of radio detector device program with display of radargram and graphical image at detection of living object by its breathing To enhance efficiency of RD-400 radio detector device application, the program provides a series of options, which function and use are described below. Calling up of required option is performed 6 by pressing of relevant button. “Configuration” option (Figure 4.6) allows: · selecting the language (English, Chinese) of captions in main window of RD-400 program. · configure settings of device manufacturer (“Factory settings”). Figure 4.6. “Settings” menu of RD-400 radio detector device program “Distance” option - meant for selection of sounding distance of RD-400 radio detection device (3 m, 7 m, 15 m, and 30 m) Figure 4.7. Figure 4.7. “Distance” option of RD-400 radio detection device program “Time of analysis” option - meant to set up time period (Figure 4.8), during which the program analyses spectrum of reflected signals. Range of analysis time variation is 15, 30, 60, and 120 s. In the course of prospecting works under rough conditions, it is necessary to increase the time of analysis to 60-120 s. 7 Figure 4.8. “Time of analysis” option of RD-400 radio detection device program “Blind zone” option - meant to adjust distance value (Figure 4.9) in a close zone of device in order to decrease probability of false detections. The size of “Blind zone” changes to a distance of 1.0 m with a step of 10 cm, further on the step of change is 0.5 m. The main program window area of “Blind zone” gets filled with green transparent color. Button of zone increase Display of size of “Blind zone” Button of zone decrease Figure 4.9. “Blind zone” option of RD-400 radio detection device program “Sensitivity” option - meant to change the device sensitivity (Figure 4.10) at detection of objects by their breathing. There are eight grades of sensitivity in the program from 1 to 8; 8 stands for the highest sensitivity. Button “+” increases sensitivity of the device, and button “-” decreases it; additionally a numeric value displays the grade of sensitivity. Increase of sensitivity at sounding of medium which is not complex by its electrophysical properties leads to rise of false random 8 detections. Figure 4.10. “Sensitivity” option of RD-400 radio detection device program “Medium” option - is selected (Figure 4.11) depending on nature of medium, which the sounding penetrates (concrete, air, snow). Selection of medium affects the correctness of determination of a distance from the radio detection device to an object detected by its breathing Figure 4.11. “Medium” option of RD-400 radio detection device program RD-400 radio detection device detects the objects not only by their breathing, but also by their motion. The window of device program can be presented in two forms (Figures 4-12 to 4.13). In the first case, detection of a mobile object is displayed in the form of the “walking man”cryptogram, which moves on the screen in parallel to the scale of distances depending on change of distance from the device to the detected moving object. In the second case, radargram is supplemented, on which the motion trajectory of detected object moves relative to the device. 9 Figure 4.12.

Charging the power supply unit Before start of the charging procedure, it is necessary to unplug connector (item 1 Figure 4.1) from the power supply unit. 10 1 2 Figure 5.1. Upper panel of RD-400 radio detection device Sequence of BP-9/12 power supply unit charging: 1. Connect ZU-9 charger to 220V, 50Hz mains. 2. Switch on power supply unit. 3. Connect charger to the power supply unit. 4. Prior to charging, the red LED flashes (test phase) over 2-3 seconds, then it stays lit. Charging of completely discharged power supply unit takes not more than 10 hours. 5. When green LED lights up, disconnect the charger and power supply unit in reverse order. If it is necessary to completely disconnect BP-9/12 power supply unit from the radio detection device, perform the following steps: 1. Disconnect the connector, item 1 (Figure 4.1) 2.
