摘要： An apparatus for localizing a sound source includes at least two rotatably arranged microphones, a drive formed to set the microphones into rotation, and an evaluator. The evaluator is formed to receive microphone signals of the at least two microphones, while the at least two microphones are moving, and to obtain information on a direction from which sound arrives from the sound source or information on a position of the sound source, using the microphone signals obtained during the movement of the microphones.

摘要： A system and method for scanning an array of acoustic transducers. A plurality of mixers are provided, one for each of the acoustic transducers. An acoustic delay line having a plurality of surface wave taps, one for each of the mixers, is also provided. One of the plurality of acoustic transducers and one of the surface wave taps are coupled to each of the mixers. In accordance with one embodiment, a signal is propagated down the acoustic delay line which has a pulse width less than the spacing between the surface waves taps so that only one mixer at a time has the delay line signal applied thereto. If a transducer signal and a delay line signal coexist at one of the mixers an output signal at the sum and/or difference frequency of the two signals is generated and detected. In accordance with another embodiment the delay line signal has a pulse width such that the signal is simultaneously applied to all of the surface wave taps and hence to all of the mixers. The spacing between the surface wave taps is even so that there is a linear phase variation among the delay line signals applied to the various mixers. The signals across the mixers are summed so that substantially no output is coupled out of the mixers until the frequency of the delay line signal is adjusted such that the linear phase variation of its signals applied to the mixers cancels the phase variation of the signal received by the transducer array. The system thus can function as a phase detector.

摘要： An improved apparatus for providing a polar coordinate indication at an image frequency which produces still pictures, e.g. on a cathode-ray tube, of a scanning function A g(x) furnished by an electronic scanner by scanning received acoustical or electromagnetic signals, e.g. from sonar or radar system, wherein A is the signal intensity and the independent variable x is the angle of incidence phi ; the frequency for some other parameter of the received signal, wherein the independent variable x is indicated by the angular deflection of the indication and the signal intensity A is represented by the radial deflection of the indication. Various alternative types of representations of the scanning function utilizing this scheme are provided. According to one type of representation the course or shape of the scanning function curve may be indicated with respect to a zero reference circle, preferably with the area beneath the curve also indicated or brightened in the case of a cathode-ray tube indicating device. According to a further type of representation the maximum values of all or selected scanned signals are determined and indicated as radial lines or spokes. Apparatus is also provided for simultaneously presenting both of these types of indications or indications representing different types of scanning functions in different sectors of the image field of the polar indication.
