OBJECT AND MOVEMENT DETECTION

Motions, positions or configurations off, for example a human hand can be recognized by transmitting a plurality of transmit signals in respective time frames; receiving a plurality of receive signals; determining a plurality of channel impulse responses using the transmit and receive signals; defining a matrix of impulse responses, with impulse responses for adjacent time frames adjacent each other; and analyzing the matrix for patterns (22) corresponding to the motion position or configuration.
