SCAN PERIPHERAL:
GROUND PENETRATING RADAR
(UWB SENSOR)

UWB TECHNOLOGY: Detection of movements of buried people

The SCAN device is a UWB ground penetrating radar sensor (also called 'seismic/acoustic instrument') designed to detect and locate survivors buried under wreckage by detecting movements. It is used during the technical search phase of USAR rescue and rescue-clearance operations. The SCAN ground penetrating radar features Ultra Wide Band (UWB) technology that scans the surface of the rubble to search for the movements of conscious or unconscious victims up to 30 m unobstructed. This search ground penetrating radar detects most movements of a conscious or unconscious person through 50 cm of concrete, wood, roof tiles, glass, plaster, bricks, sand, floor tiles, bitumen, plastics and more. (However, note that electromagnetic waves cannot pass through metal surfaces or water).

UWB ground penetrating radar designed for the field

The radar aerial and associated electronics are housed in a small waterproof and shockproof case. It's the smallest in its class! Being compact, it can be handled in small spaces. It has an interchangeable Lithium-Ion battery giving it 4 hours field running time. A battery level indicator can be seen on the outside of the sensor to avoid opening it in the field. The SCAN victim detector is WiFi-connected with a range of 30 m, making it easier to handle in the field. However, it is possible to connect a cable if there is interference in the search area.

2 search modes: Automatic or Manual

The SCAN UWB ground penetrating radar has 2 search modes: - Automatic: Automatic analysis of several predefined areas to detect up to 7 living people. - Manual: Manual pre-determined analysis with search area selection. The depth at which the movement is detected is indicated. The device also displays whether they are weak movements (e.g. breathing) or strong movements. An oscillogram is used to view and track movement in real-time, illustrated by a sine wave. Repeated wide oscillations indicate a repeated movement (e.g. a victim tapping). The depth of oscillations indicates the intensity of the movement (strong or weak). The frequency of movements helps us deduce whether or not it is a human.

User-friendly graphic interface

Each item has been designed to make rescuers' work easier: - Compact and lightweight control box, - Extra-wide colour screen, - User-friendly graphic interface, - Intuitive menu, - Weak or strong movement indicator, - Oscillogram function to view frequency of the movement detected, - Selection of minimum (start) and maximum (end) search depth, - AUTOMATIC search mode (automatic analysis of selected depth in 3 m bands), - REAL-TIME search mode (manual control of various parameters to display movement detection in real time) - Records movement detection data, etc.

PRODUCT SPECIFICATIONS

The SCAN device is an Ultra Wide Band radar sensor (also called 'seismic/acoustic instrument'), movement detector through wreckage. Developed with victim location specialists, the SCAN device is used during the technical search phase of USAR search-clearance operations to detect and locate the movements of conscious or unconscious victims through various materials in collapsed buildings.

It uses UWB (Ultra Wide Band) technology that probes the surface of rubble to identify movements.
Its excellent sensitivity can detect irregular movements such as the movement of a finger, or regular movements as precise as the chest movements of a breathing victim, even if unconscious!

The ultra-sensitive sensors detect even the smallest movements and indicate the precise depth at which the victim is located. The frequency of movements is also analysed to determine whether or not it is a human life.

It sends electromagnetic waves through materials to detect variations in movements.
It detects movements through 50 cm of concrete, wood, roof tiles, glass, bricks, plastics and more. (However, note that electromagnetic waves cannot pass through metal surfaces or water).

It meets operational requirements since many international expert search and rescue teams (INSARAG, Civilian Security, FEMA Task Force, USAR teams, UKSAR, SAR, NGOs, etc.) use LEADER search equipment.
