Electromagnetic obstacle detection arrangement, e.g. for use with motor vehicle parking systems, comprises an antenna and a signal processing circuit that detects changes in the antenna feedback signal due to obstacle presence

摘要

Obstacle detecting device comprises an antenna, a signal processing circuit, a computer program and a transceiver for transmission of an electromagnetic signal via the antenna. The input to the signal processing circuit is a feedback signal received from the antenna and transceiver. The alteration in the detected feedback signal is analyzed by the signal processing circuit in order to detect the presence of an obstacle.
