Abstract
The invention relates to a method for detection of motion of the surface of an object by means of a detection device, the object being stationary during a detection process, and situated in a space on the opposite side of a wall in relation to the detection device, and having a relative dielectric constant εr greater than 1.1. The method comprises steps of transmitting radar signals and receiving radar signals reflected by the object, and if a motion has been detected, in addition visualising the motion in a three-dimensional combined radar model and data model. The invention also relates to a detection device for carrying out the method.
