  • Page 27: Sensitivity Function

    4.3 Sensitivity function This function helps adjust the sensitivity of the UWB sensor to be more or less sensitive. Sensitivity can be adjusted from 0 to 4. 0 = Reduced sensitivity to help ignore major surrounding movements which are too clear. However the device will be less successful in detecting weak movements.

  • Page 28: Minimum Distance Function

    4.5 Minimum distance function Selects minimum search depth located at the start of the detection cone. Minimum search depth (Mini) By default the Mini is set to 0m (0ft). When adjusting the minimum distance, the difference between the minimum and maximum does not change, the maximum distance is therefore modified at the same time as the minimum depth.

  • Page 29: Screen Brightness Function

    Adjust the “Mini” and “Maxi” depths to define the search zone. Go to the menu and select. Launch the “Real time” mode by pressing An orange triangle starts to flash at the top of the screen. The device takes 15 to 20 seconds to start before starting the scan.

  • Page 30: Automatic Mode Function

    To stop the search, select the “Real time” icon again and press The flashing orange triangle disappears. During a search in “Real time” mode, if several people/movements are found in the previously determined detection zone (cone), only the largest person/movement will be used and displayed.
  • Page 31 => Total displayed in the cone: 3 victims/movements: After analysing each section, the pointer (1) is positioned on the maxi of the section. 2 - Pointer Once the full scan is complete, the pointer is distance positioned at the level of the closest detected 3 - Oscillogram movement to the sensor, indicating this depth (2).

  • Page 32: Source Function

    For a 0-30m search, LEADER Scan can detect up to 10 people: 1 per section (0-4, 4-8, 8-12, 9-12, 12-16, 16-20, 20-24 and 24-26m). The scan can last up to 10 minutes in this case (less if the victims are detected before 1 minute in some sections) For a 0-10m search, the device will divide the cone into 0-4, 4-8 and 8-10m.

  • Page 37: Use In The Field

    The LEADER Scan sensor can detect movement in a cone area in a vertical position. The rubble density extends the detection angle, as the debris acts like a lens for the UWB antenna. The UWB sensor search angle is 90°...
  • Page 38 From the determined grid pattern, the operator could move the pointer to a specific path as shown in the images above by applying the overlap described in the next paragraph: To have the clearest possible image of the situation, the operator must move around the controlled space as much as possible by positioning the sensor vertically and also, if the conditions allow, horizontally from other locations.

  • Page 39: Detection Through Materials

    The compact size of the UWB sensor allows it to be inserted into cavities and gain several centimetres to increase the percentage success of detecting a victim. 5.2 Detection through materials ➢ The UWB sensor cannot detect through: - Metal plates. - Water, puddles and saltwater.

  • Page 40: Recommendations

    LEADER Scan cannot detect a victim who is behind or under a solid metal screen or water. The device cannot detect through damp conducting bodies, like wet clay. Damp soil is not ideal for UWB scanning as water acts as a shield against waves.

  • Page 41: Interpreting The Signal On The Oscillogram

    5.5 Interpreting the signal on the oscillogram The LEADER Scan combines a detection zone (cone) and an oscillogram (graph) of detected movements on the screen. Movements are interpreted on the curve. (Number of movements and intensities of these movements). If the curve is sine curve, the user is in the presence of repeated movement (breathing, victim tapping regularly...).
  • Page 42 The scale of the Y axis adapts to the signal intensity to balance the heights of the curve on the screen and therefore the movements detected in the field. The LEADER Scan remains one of several tools used when searching for buried victims. The emergency worker must understand that they must rely on other search equipment or...

  • Page 43: Automatic And Real Time Modes

    3 search sub-zones (0-3m (0-9ft), 3-6m (9-18ft), 6-9m (18-27ft)), it takes up to 3 minutes to complete the search (1 minute to scan each 3m section). The automatic mode search time is longer but has the advantage of being easier (the user sees the search result on the screen).

  • Page 44: Define The Search Distances

    5.7 Define the search distances Modify the search distances based on the debris composition in the field and depending on the depth to be analysed. Real time search mode: A closer search zone (Mini-Maxi) helps provide higher sensitivity in the selected zone and less “noise” from the outside. If the user selects 2-5m (6-15ft), the noise at a distance under 2m (6ft) and a distance over 5m will be lower.
