Short-Range Radar

Like microwave imaging, the method used in the short-range radar belongs to the family of microwave sensors. In this procedure, several sensors that act as transmitters and receivers at the same time are used to emit and absorb electromagnetic waves, which initially generates an overall image of the environment and the bodies contained in it. By repeating the procedure, changes in the reference space can thus be recognised and the corresponding distances, movements and speeds of the individual objects can be detected in the evaluation.

Based on this function, the short-range radar has previously been used specifically in air space monitoring, environment analyses and vehicle technology. The particularly developed fine sensors and the further development of the system-technical properties in the m:explore, however, permits development of further application areas of this measuring procedure. The short-range radar by Ilmsens thus can be used in the medical area to monitor different vital functions such as pulse and breathing. On the other hand, the innovative system can be used in geological applications for characterisation of soils and identification of earth layers or buried objects, such as mines or historically valuable artefacts of extinct civilisations.

Short-Range Radar with the m:explore

The high-resolution short-range radar in the m:explore permits detection of minute movements. The system can perceive, display and evaluate movements through objects such as walls and clothing. The presence detector is used both in monitoring of vital data, e.g. of persons needing help in nursing facilities or workers in risky deployments, but also to find materials and objects in the soil.
The short-range radar of the m:explore is characterised by the system's high stability over time. Very small runtime differences are identified reliably and permit conclusions to the position and position changes, and thus eventually to movements, without requiring direct contact and without severely compromising a person's privacy. For example, persons can be localised in rooms, their vital signs such as breathing and heartbeat, can be monitored, and tiny animals such as insects and other pests, can be reliably detected in working materials and walls.
The short-range radar can also be used as a georadar. The cascading option of the sensors permits development of large sensor arrays and determination of density differences in the soils. Thus, non-metal objects in the soil, including anti-personnel mines or archaeological finds, can be reliably located.
