摘要： In Higher Order Ambisonics, a problem is the tracking of time variant directions of dominant sound sources. The following processing is carried out: from a current time frame of HOA coefficients, estimating a directional power distribution of dominant sound sources, from said directional power distribution and from an a priori probability function for dominant sound source directions, computing an a posteriori probability function for said dominant sound source directions, depending on said a posteriori probability function and on dominant sound source directions for the previous time frame, searching and assigning dominant sound source directions for said current time frame of said HOA coefficients.

摘要： The invention relates to a method and an apparatus for estimating the shape of an acoustic trailing antenna (12), wherein the shape is estimated using Kalman filtering. First of all, this involves the deterministic component (u(k
i )) of the state equation of the Kalman filter being set to zero. In addition, successive discrete times (k
i ) are predefined and, at the predefined times (k
i ), a respective estimated shape for the trailing antenna (12) is described by a model-based state vector (x)(k
i ). In this case, the model-based state vectors (x)(k
i ) are ascertained by the estimated timing response of a mechanical model (24) of the trailing antenna (12) and by movements in a traction point (16) for the trailing antenna (12) that are assumed to be known. The discrepancy in the respective current model-based state vector (x)(k
i ) is determined for one or more preceding model-based state vectors (x)(k
i-1 ), is considered as a current matrix (F)(k
i ), and the current transition matrix (F)(k
i ) is periodically updated for the Kalman filtering with the ascertained matrices (F)(k
i ).

摘要： Security events, such as gunshots may be determined using hybrid sensors. The hybrid sensors have at least two different elements that are sensitive to the security event, such as conventional microphone and a fiber optic microphone, which, in the case of a gunshot, permits a better scanning of the report of the gunshot to better determine its direction, signature features, and time of arrival. Additionally, sensor can be employed having multiple elements that are sensitive to a security event where at least one of the elements is not coplanar with the rest. This displacement along an orthogonal axis may be used to improve the ability of a network of such sensors to determine the direction and origin of a security event in a three dimensional system.

摘要： A method and system is described for reducing unwanted noise components/interfering targets detected through an ambiguous beam-steer direction, such as the ambiguous `back-lobe' of a sensor array. A pressure sensor array 52 and a plurality of pressure gradient sub-arrays 54 1-N are beamformed individually at processing stages 56, 58 1-N to derive signals indicative of directional responses, one from each group or sub-group. The signals are scaled and weighted (60, 62 0-N ) and processed to define a cardioid beam with nulls pointing in the ambiguous beam-steer direction.

摘要： The invention relates to a device (6) and a method (54) for acoustically monitoring at least one listening sector (34), which lies in a monitoring plane (UE) that can be monitored by means of a sonar system. The sonar system comprises a receiving antenna (38) having a plurality of underwater sound receivers (40), wherein by means of the receiving antenna (38), underwater sound signals can be received and received signals can be generated from the underwater sound signals. The sonar system further comprises a direction generator (8) and an audio signal processing unit (10), which together can be used to generate an audio signal (60) that acoustically reproduces the listening sector (42) from the incoming signals. The device (6) comprises a main listening direction setting means (23), by means of which a main listening direction (44) lying in the monitoring plane (UE) can be adjusted by swiveling relative to a reference direction (BR) fixed to the antenna. According to the invention, the device (6) comprises a line of sight detection means (12), by means of which a line of sight (16) of one eye (14) or both eyes of an operator (4) can be detected. In addition, the main listening direction setting means (23) is designed in such a way that by means of the main listening direction setting means (23), the main listening direction (44) can be set according to the detected line of sight (16) so that the invention enables a simple setting of the main listening direction (44) or of a direction angle.

摘要： A signal processing apparatus includes: a learning processing unit (110) that finds a separating matrix for separating mixed signals in which outputs from a plurality of sound sources are mixed, by a learning process that applies ICA (Independent Component Analysis) to observed signals including the mixed signals; a separation processing unit (123) that applies the separating matrix to the observed signals to separate the mixed signals and generate separated signals corresponding to each of the sound sources; and a sound source direction estimating unit (125) that computes a sound source direction of each of the generated separated signals. The sound source direction estimating unit (125) calculates cross-covariance matrices between the observed signals and the separated signals in corresponding time segments in time-frequency domain, computes phase differences between elements of the cross-covariance matrices, and computes a sound source direction corresponding to each of the separated signals by applying the computed phase differences.

摘要： Zum Bestimmen der Einfallsrichtung empfangener Schallimpulse aus Empfangssignalen einer Sonarbasis werden Richtcharakteristiksignale durch Laufzeitkompensation der Empfangssignale gebildet. Um eine Anzeige der Einfallsrichtung bei Empfang von Schallimpulsen über Grating-Lobes auszuschließen, wird erfindungsgemäß die Einhüllende jedes Richtcharakteristiksignals mit impulsförmigen Signalinhalt gebildet und die Steigung der Einhüllenden bestimmt. Die Einhüllende mit der größten Steigung kennzeichnet die Empfangsrichtung des Schallimpulses. Dieses Verfahren ermöglicht den Einsatz von Seitenantennen und Hufeisenantennen zum Bestimmen der Einfallsrichtung von Schallimpulsen und gewährleistet eine Unterdrückung von Fehlanzeigen durch Scheinziele.

摘要： Zum Bestimmen der Peilung eines Ziels, das ein Geräusch abstrahlt oder einen Schallimpuls reflektiert, wird eine Winkelfunktion aus Gruppensignalen einer Peilanlage als Abtastwerte über Hauptempfangsrichtungen ihrer Richtcharakteristik als unabhängige Variable gebildet. Ihr Maximum liefert die Peilung. Um auch bei geringem Nutz/Störverhältnis der Gruppensignale und/oder bei Vorliegen zweier dicht benachbarter Ziele eine Peilung und Zieltrennung zu erhalten, wird die Winkelfunktion mit einer Referenzfunktion verglichen, im Winkelbereich durch Korrelation, im Raumfrequenzbereich durch Phasenvergleich ihrer Spektren.
Das Verfahren ist vorteilhaft in der Wasserschall- und Luftschalltechnik zum Peilen von Fahrzeugen geeignet.
