Designated use 

The UMRR general purpose medium range radar is suitable for any application where the 

distance to and relative radial speed of large objects has to be measured.  
 
Typical applications are:  
 

Automotive: measure shortest distance to obstacle. 
Robotics: measure shortest distance to obstacle. 
Security: detect motions and measure distance to moving object. 

Traffic management: detect moving objects, count those, measure speed and measure 
distance to moving object. 
Cranes: measure distance to ground. 

Aircraft: measure distance to ground. 
 
The detection range depends on object size. Very large reflectors can be detected at a range 
of more than 500 m.
