Apparatus and method for Horchpeilung

The invention relates to a device (6) and a method (54) for monitoring at least one acoustic listening sector (34), which lies in a monitorable by means of a sonar installation monitoring level UE. The sonar installation has a reception antenna (38) having a plurality of water sound pickups (40), the received signals can be generated from the waterborne sound signals by means of the receiving antenna (38) of water was added and sound signals. The sonar system further has a beamformer (8) and an audio signal processing unit (10) can be generated by means of which acoustic imaging together from the received signals a Horch the sector (42) audio signal (60). The device (6) has a Haupthorchrichtungseinstellmittel (23) by means of which a lying in monitoring level UE main listening direction (44) can be adjusted by pivoting with respect to a fixed reference antenna direction BR. According to the invention, the device (6) to a viewing direction detecting means (12) by means of which a viewing direction (16) of an eye (14) or of both eyes of an operator (4) detectable. In addition, the Haupthorchrichtungseinstellmittel (23) is designed such that the main listening direction (44) in dependence on the detected viewing direction (16) can be adjusted by means of the Haupthorchrichtungseinstellmittels (23), so that the invention provides a simple adjustment of the main listening direction (44) or a bearing angle ...
