Short-Range Radar

A Look behind the Scenes

Use Cases

 

Vital data acquisition

 

 

Motion detection (large dynamic range enables detection of very small and large objects)

 

   

Moisture determination (e.g. in textiles)

 

 

Defect detection (e.g. in salt mines, sewers, tunnels)

 

 

Object detection (e.g. vegetables in soil, carcinoma tissue)

 

 

Presence detection

 

 

360° short-range radar

 

    Driver-assistance systems

Principle of Operation

The short-range radar operates according to the well-known radar principle in which the propagation time of a transmitted wave reflected by an object is measured.

 

The distance from the object to the sensor can be determined from this roundtrip time. By further evaluating the received signal, conclusions regarding the velocity or size and type of the examined object can also be drawn.

 

The short-range radar from Ilmsens is characterised by the system's high stability over time. Very small propagation time differences are identified reliably and conclusions regarding position and position changes can be reached without requiring direct contact. Even rain, fog or dirt in the signal path will not create any problems.

 

Thanks to the special technology used, there is almost no self-interference and the receivers are robust with regard to other types of transmitters. There is also no degradation of the high measurement rate for detecting fast objects, even if they are very close to the radar.
