An echo-signal monitoring device having a plurality of transceiver units for transmitting signals and receiving the echoes reflected by an external object and an analyzer unit for estimating the distance from the monitoring device to the external object on the basis of the received echoes is characterized in that the device has an operating mode for calculating the relative position of the transceiver units from one another on the basis of the reflected echoes.

Monitoring device and method using echo signals

The signal echo monitoring device includes a transmitting unit ( ) for broadcasting a transmitted signal (s(t)) which is a group of randomly generated pulses, a receiving unit ( ) for receiving an echo signal (e(t)), reflected by an object ( ), of the transmitted signal and a combined control and evaluation unit ( ) including a device ( ) for jointly evaluating the transmitted signal (s(t)) and the echo signal (e(t)) with an integrated adaptive filter ( ). The adaptive filter ( ) automatically calibrates its impulse response b(t) and may be a digital filter.
