Ultrasonic sensor unit

An ultrasonic sensor unit, comprising:

• a first ultrasonic element;
• and
• a logic unit;
• wherein the first ultrasonic element is configured to emit and/or receive at least one ultrasonic wave;
• wherein the logic unit is configured to generate an echo signal and a trace signal based on the emitted and/or received at least one ultrasonic wave;
• wherein the logic unit is configured to predict at least one further ultrasonic wave and a further echo signal for a further trace signal based on the echo signal and/or the trace signal using a Kalman filter;
• wherein the logic unit is configured to assign the further ultrasonic wave, and/or the further echo signal. and/or the further trace signal to the emitted ultrasonic wave, and/or the echo signal and/or the trace signal, using a Kuhn-Munkres algorithm.
