8 Detecting apparatus JP15291688 1988-06-20 JPH01318984A 1989-12-25 FUKUOKA ITSUO; NAGANO HIROSHI
PURPOSE: To amplify the received outputs of many wave receiving elements with a small number of preamplifiers by sequentially switching first and second switching means, selecting the received outputs of the wave receiving elements in an order of arrangement, and amplifying and sending out the outputs through the preamplifiers. CONSTITUTION: Wave receiving elements 1-120CH are equally divided into (m) pieces in (n) sets. A frequency shifting means is composed of a first switching means SWa, a second switching means SWb and a switch control means. The first switching means SWa selects any one output of the received outputs at the same order from the wave receiving elements in the (n) sets. The selected output is inputted into the respective (m) pieces of preamplifiers P1-P60. The preamplifiers are provided so as to match the corresponding numbers in the sequence. The second switching means SWb selects the outputs of the (m) pieces of the preamplifiers and sends the outputs to a received-wave-beam forming means 1. The switch control means sequentially switches the first and second switching means so as to select the received outputs of the wave receiving elements 1-120CH in the order of arrangement. The signals which are amplified in the preamplifiers P1-P60 are sequentially outputted. COPYRIGHT: (C)1989,JPO&Japio

12 Own doppler nullifier for sonar system US196306 1980-10-14 US4316269A 1982-02-16 Adrian van't Hullenaar, deceased
There is described a digital sonar receiver having a novel beamformer, own doppler nullifier (O.D.N.), and adaptive time varied gain controller. The beamformer interrogates a multi-element transducer by utilizing an interleaved sampling scheme which samples the elements in the transducers array sequentially, in such a fashion that continuous, uniformly spaced samples are obtained. The samples are subsequently converted into digital format, weighed and summed. The O.D.N. eliminates the own ship's doppler effect on the beam output signal resulting in a half beam output signal representative of the target doppler. The O.D.N. offsets the frequency of the beam output signal and a digital generated signal representative of the own ship's doppler. The O.D.N. multiplies these two offsetted signals resulting in a signal lying in each of the sum and difference frequency bands for which the signal lying in the difference frequency band corresponds to the target doppler. The adaptive time varied gain controller varies the gain of preamplifiers at the input of the sonar receiver to be inversely proportional to the momentary average reverberation level of the medium in which the receiver operates. The adaptive time varied gain control apparatus initially sets the gain of the preamplifiers to be inversely proportional to a standard reverberation curve during the first ping-cycle and subsequently updates the gain of the preamplifiers during each successive ping-cycle by computing a gain correction from the average value of a predetermined number of beam output signals.

15 Indicator for detected information JP11800480 1980-08-26 JPS5740664A 1982-03-06 IINO HIROSHI; SASAKURA TOYOKI
PURPOSE: To produce a wave-receiving beam by means of a simple structure, by a method wherein, in an indicator, such as fish detectors, direction finders, an arrival signal is received so that the frequency of the arrival signal is caused to deviate, and an output signal so obtained is pulse-compressed for the indication. CONSTITUTION: A wave-receiving signal, caught by a wave-receiving means 1 consisting of an ultrasonic vibrator 6 which performs an uniform circular motion, is fed out to a pulse compressing means 2. The pulse compressing means 2 consists of a matched filter having a frequency - time characteristic being reverse to that of a wave-receiving signal, and the wave-receiving signal is pulse-compressed to be fed out to an indicator 3. The output signal of the pulse compressing means 2 includes only a signal arriving from a given direction, and thus, a wave-receiving beam, directing a given direction, is produced. Said wave-receiving signal 1 and the indicator 3, consisting of a CRT and the like, are driven in synchronism with each other by means of a controller 4 to indicate a surrounding condition in the indicating surface of the indicator 3.
