11 Sonar direction finding US07578528 1990-08-20 US06473363B1 2002-10-29 Emerson Hardy Oetzmann
A method of determining the bearing of a source of a sonar signal comprising determining the phase of a cyclic variation of the output signal of a sonar detector having a directional characteristic which occurs as the orientation of the detector, and hence its characteristic, is rotated. In a preferred method the sonar detector output is spectrum analysed at each of a plurality of different orientations of the detector to provide for each orientation a signal representative of the amplitude of a component of the signal produced by the source of a chosen frequency. The signals so obtained are then arranged to form a time series of samples of said component as the orientation of the detector is rotated at a predetermined frequency and the time series used to analyse the spectrum of the signal defined by the time series and thereby determine the phase of the sinusoidal component of the signal defined by the time series at the predetermined frequency. Apparatus for carrying out the method is also disclosed.
12 Circuit arrangement for the formation and processing of group signals US331885 1981-12-17 US4433397A 1984-02-21 Egidius Arens; Ravin Patel
A circuit arrangement for forming a succession of group signals in the ranging art from received signals originating from an array of adjacent signal receiving transducers, each successive group signal being associated with a respective group characteristic and being based on the signals received by a respective group of adjacent transducers forming part of the array. The succession of group signals is processed to form a representation of the mean, or average, value of a predetermined number of successive group signals, and a representation of the ratio of the value of one of the group signals of that predetermined number of signals to the mean value is produced.

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.
15 Circuit arrangement for forming a time sequence of signals US26810472 1972-06-30 US3810082A 1974-05-07 ARENS E
A circuit arrangement for forming a time sequence of group signals in the ranging art, particularly in the sonar art, and preferably for a receiving system for signals impinging in a planar wave front, for a momentarily effective characteristic of a group of adjacent, possibly overlapping group characteristics obtained from received signals originating from a number of adjacent transducers from a larger plurality of transducers, in the receiving system. The group signals are formed by varied, quantized time delays determined by the geometrical arrangement of the transducers and by the propagation speed of the impinging signals in the transmission medium. The circuit arrangement employs a single memory circuit having arrangements for the reading in and for the directed reading out of received signals, and a subsequently connected adding circuit of whose output the group signals of the group characteristics appear. An input circuit is provided for the repeated, consecutive interrogation of the respective momentary received signal from each individual transducer of a plurality m of the adjacently positioned transducers. The input circuit is operative for reading the received signals, via a read-in point, in succession and in the same sequence into the memory circuit within which each read-in received signal consecutively occupies in steps memory locations which are further removed from the read-in point. The memory circuit is provided with a number of memory locations which at least and preferably are determined by the maximum time delay for the first interrogated received signal. An output circuit is provided for the destruction-free read-out of the stored received signals from a number of n memory locations which correspond to the required time delays with respect to the read-in point. The adding circuit is connected to the output circuit and the group signals derived from the received signals appear in succession at the output of the adding circuit.
