摘要： PROBLEM TO BE SOLVED: To keep constant width of orientation even if a frequency of a sonic wave to be measured is changed. SOLUTION: An array body 5 includes an elastic body belt 9 provided by arraying a required number of receiving elements 2 and an extendable mechanism 10 for extending/contracting the elastic body belt 9. A receiving array apparatus includes: a rotation speed sensor 6 for detecting a rotation speed of a noise source 3; a rotation speed analyzer 7 for calculating a frequency of a sonic wave of noise from the noise source 3 based on a signal of the rotation speed sensor 6; and an array controller 8 which gives a control command to the array body 5 in accordance with the frequency, calculated by the rotation speed analyzer 7, of the sonic wave of noise from the noise source 3. When the rotation speed of the noise source 3 is low and the frequency of the noise is low, array intervals of the receiving elements 2 in the array body 5 are increased. When the rotation speed of the noise source 3 is increased and the frequency of the noise becomes high, the intervals of the receiving elements 2 are reduced, thereby maintaining the width of orientation while changing the entire size of lines of the receiving elements 2.

摘要： A transceiving device includes a transmission signal generating module for generating a transmission signal that is frequency-modulated by a predetermined frequency sweep width, a transceiver module for transmitting a pulse signal having substantially the same waveform as a waveform of the transmission signal and receiving an echo signal corresponding to the transmission signal from a detection range, and a pulse-compression filter for pulse-compressing the echo signal received by the transceiver module. The pulse-compression filter has an input/output characteristic. The characteristic has, when the pulse-compression filter is inputted with an input signal having substantially the same waveform as the waveform of the transmission signal, a window function shape such that a phase spectrum of an output signal corresponding to the input signal is linear and an amplitude spectrum of the output signal does not have a frequency component other than a frequency band with which a frequency sweep is carried out.

摘要： PROBLEM TO BE SOLVED: To provide apparatuses and methods for accurately finding out a direct/indirect ratio estimation value of an acoustic signal.SOLUTION: A direct sound direction power estimation part obtains a power estimation value of a direct sound direction signal obtained by performing processing for passing only a signal component arriving from a direct sound source direction by predetermined beam-former achieved by a microphone array 41. A reverberation sound direction power estimation part obtains a power estimation value of a reverberation sound direction signal obtained by performing processing for passing a signal component arriving from a direction other than the direct sound source direction by beam-former having the same directivity shape as the beam-former and set so that a main beam direction avoids the direct sound source direction. A direct/indirect ratio calculation part 44 obtains a direct/indirect ratio estimation value DRR expressing a ratio of the power estimation value of a direct sound to the power estimation value of the reverberation sound direction signal by using a power estimation value of a frequency area signal and the power estimation value of the reverberation sound direction signal.

摘要： PROBLEM TO BE SOLVED: To efficiently detect an underwater vessel from broadband radiated sound, such as friction sound between the underwater vessel and water (sea water, fresh water or mixture water of the two), even when operation sound of a propelling machine of the underwater vessel is low.SOLUTION: An acoustic sensor 110 converts acoustic waves generated from an underwater vessel 300 existing under water to electric signals. A directivity forming section 150 forms cardioid type directivity for each prescribed frequency component on the basis of the electric signals. A directivity ratio calculating section 160 calculates a directivity ratio, which is a ratio of a signal level in a maximal sensitivity direction to a signal level in a minimal sensitivity direction for each of the prescribed frequency components, on the basis of the cardioid type directivity formed by the directivity forming section 150. A directivity ratio distribution generating section 170 composes the directivity ratio calculated for each of the prescribed frequency components by the directivity ratio calculating section 160, and generates a directivity ratio distribution showing a distribution of the directivity ratio for each of the frequency components.

摘要： PROBLEM TO BE SOLVED: To enhance discriminability for an azimuthal direction, suppress generation of false images, and prevent lowering of the precision of azimuthal direction detection and lowering of sensitivity. SOLUTION: A transmitting signal generating circuit 120 generates a first and second two burst waves of transmission frequencies whose difference changes linearly for example in accordance with an azimuth which makes the reference azimuth of a transducer 101 a reference, and an amplification circuit 103 drives a predetermined vibrator of the transducer 101 by the signals. A preamplifier 105 amplifies received signals produced by the first and second burst waves, a prefilter 106 allows only a predetermined band to pass, an A/D converter 107 performs conversion to a digital data string, and a beam former 108 forms a received beam in a predetermined azimuth. A correlation filter 121 performs filtering processing determined by the transmission frequency difference according to the azimuth, with respect to a composite waveform generated from a composite reception signal by the first and second burst waves.
