摘要： PURPOSE:To enhance the detection exactitude of an acoustic signal even when an S/N ratio is bad by utilizing that learning is not converged with respect to one having no regularity and one having no correlation by a neural network and detecting a target in a state divided into many stages. CONSTITUTION:A learning judging part judges that learning is converged when the sum total of the change quantities of the product of the loads of bonded one layer and two layers is a threshold value or less. When it is judged that learning is converged in the learning judging part 4, a reverse load calculation part 5 calculates the reverse load of a network. In a target detection part 6, the pattern matching of the target signal preliminarily learned in a neural network and the signal calculated by the reverse load calculation part 5 is executed to judge whether the target signal shows a target. By this method, the possibility detecting the target from the signal buried in noise becomes large.

摘要： PURPOSE:To make a device for eliminating direction estimating errors smaller in size and simpler in constitution, by analytically calculating the errors from the difference in previously given phase responses, positional coordinates of an array element, weighting coefficient of a beam former, and a power spectrum in the vicinal direction of a signal source. CONSTITUTION:Signals from a signal source are received by arrays 11-1M composed of plural wave receivers arrayed in a space and added to each other after they are compensated for time delay and weighted by means of a beam former 4 after passing through amplifiers 2 and filters 3. On the other hand, a direction cosine error calculator 21 calculates a direction estimating error from outputs of registers 22-25, which respectively store power spectra L1-LK in the vicinity of a signal source direction alpha0, positional coordinates P1-PM of the array elements, weighting coefficients b1-bM of the beam former 4, and differences in the phase response of the array elements, and an array constant register 26. The direction estimating error thus calculated is eliminated by subtracting it at an adder 20.

摘要： PURPOSE:To obtain an underwater receiver which has a good S/N (underwater noise ratio to target sound) in a high frequency range by obtaining cardioid directivity by using a universal, inexpensive, and small-sized nondirectional receivers, resistance, capacitor, and operational amplifier. CONSTITUTION:The nondirectional receivers 2 and 3 are arranged vertically and linearly over and under a nondirectional receiver 1 at specific distance. The output of the nondirectional receiver 2 weighted by a weighting circuit 7a to generates an output 12 while passed through a +90 deg. phase shifter 4 and weighted by a weighting circuit 8a to obtain an output 11. Further, the output of the nondirectional receiver 1 is weighted by a weighting circuit 6 to obtain an output 13. The output of the nondirectional receiver 3, on the other hand, is passed through a -90 deg. phase shifter 5 and weighted by a weighting circuit 8b to obtain an output 15 and also weighted by a weighting circuit 7b to generate an output 14. Further, the outputs 11-15 are inputted to an adder 9 to obtain the output 16 of a directivity generating circuit. When a target sound arrives in a horizontal direction, in-phase and equal-level outputs are obtained from the nondirectional receivers 1-3.

摘要： PURPOSE:To enable the operator to know the existence of underwater objects rapidly and enable their positions to be measured by providing the information of all bearings similar to that of CRT display to sound hearing signals. CONSTITUTION:This adds a sonar receiving additional unit 2 to the receiving display system 1 of a conventional preformed beam sonar apparatus, wherein the additional unit 2 consists of an audible frequency oscillator group 11 of the same number as preformed beams and respectively different timbres, a modulator group 12 which amplitude-modulates the output signals of the respective channels of said oscillator group as well as a switch group 13, a signal synthesizer 14 and a changeover switch 15, with which unit the information in all the bearings may be listened to by making contact all of the switches of the switch group 13 and further shifting the switch 15 to the b side, thus when any underwater object exists in the searchable region, the signal sounds of the timbres (frequencies) corresponding to the bearings of the underwater object may be listened.

摘要： L'invention concerne les procédés de traitement des signaux d'une antenne linéaire remorquée comprenant n (de préférence 3) sous-antennes parallèles formant des multiplets d'hydrophone. On mesure (110) l'angle de roulis des multiplets pour synthétiser (101 ) des sous-antennes linéaires stabilisées. On forme ensuite (102) M v voies gisement pour chaque canal doppler avec chaque sous-antenne, et on forme enfin ( 104 ) 2 voies droite-gauche adaptatives à partir de ces sous-antennes. Elle permet de lever l'ambiguité droite-gauche avec de meilleures performances en détection et pour des antennes longues.
