163 Apparatus for ultrasonic detection of matter JP21510782 1982-12-08 JPS59105583A 1984-06-18 NIIMI KENICHIROU; MORITA KIKUZOU
PURPOSE:To prevent the contamination generation of an ultrasonic element and the interference generation of ultrasonic waves caused by multiple reflection, by arranging ultrasonic transmitting and receiving ducts each having predetermined constitution to both sides of a circular arc shaped wavy sound absorbing body at a predetermined state. CONSTITUTION:L-shaped ultrasonic transmitting and receiving ducts 6, 11 each having a refractive plate 7 mounted therein are arranged to both sides of a circular arc shaped wavy sound absorbing body 16 at an open angle theta so as to bring ultrasonic transmitting and receiving elements 4, 9 to the under side of both ducts 6, 11. By this constitution, the contamination generation of the elements 4, 9 caused by a raindrop or a stain is prevented while the interference generation of ultrasonic waves caused by multiple reflection and harmful to targe detection is prevented because of the inclination of ultrasonic transmitting and receiving wave axes due to the open angle theta with respect to the object 3 to be detected and the sound absorbing body 16.

PURPOSE:To detect an echo in a received signal securely even in case of variation in speed and variation in echo frequency and to simplify circuit constitution by providing an NB.BPF which attenuates only the echo. CONSTITUTION:The circuit 20 consisting of the NB.BPF21, a phase inverter 22, and an adder 23 functions to reduce only an echo. If an underwater sailing body varies in speed and the frequency of the echo varies, an input and an output signal to and from the NB.BPF21 has a phase difference and a detection signal (d) is outputted from a phase detector 17 and supplied through a switch circuit 25 to an integrator 18, whose integral output is supplied to an adder 26. Then, a signal (f) of frequency corresponding to its addition output signal is outputted from a VCO19 to a multiplier 12. Consequently, the frequency of the output signal (m) of the multiplier 12 is controlled to ZHz to reduce the phase difference between the input and output signals to and from the NB.BPF21.

169 Receiving method for scanning sonar JP10070781 1981-06-30 JPS582767A 1983-01-08 TAKAHASHI FUKUTAROU
PURPOSE:To enhance the receiving energy and improve the S/N, by turning plural wave receiving beams simultaneously while keeping constant angles to add the receiving signal of a preceding wave receiving beams to the signal of a reference beam. CONSTITUTION:Plural wave receiving beams including a reference beam are turned simultaneously while keeping constant angles. The echo signal received by a preceding wave receiving beam is held by means such as storage or delay until the reference wave receiving beam is scanned and reaches a position corresponding to the preceding wave receiving beam, and this echo signal is added to the receiving signal of the reference beam and is taken out. For example, turning scanning circuits 6 and 7 for preceding beam are connected to a synthesizing circuit 10 through delay circuits 8 and 9, and signals due to circuits 6 and 7 are synthesized with the receiving signal due to a turning scanning circuit 5 for reference beam.

PURPOSE:To facilitate waveform analysis by switching received wave waveform with waveform obtained by differentiating a received signal. CONSTITUTION:Received waveform 13 received by wave receiving section 1 is differentiated by a differentiating circuit 3 to make it differentiated waveform 14 and added to a trigger circuit 5. The output pulse from the trigger circuit 5 advances a counter 4 successively from ''1'' to ''3'' and switch-on signals 15, 16, 17 are distributed from a decoder 6 to analog switches 7, 8, 9. On the other hand, received waveform 13 is delayed by a delay circuit 12 so that above-mentioned signals are added to analog switches 7, 8, 9 when supplied. Consequently, while the switch-on signal 15 is sent out, a received wave signal 18 is supplied to an analyser 10 and a recorder 11. Similarly, when switch-on signals 16, 17 are sent out, received wave signals 19, 20 are supplied to the analyser 10 and recorder 11.
171 Receiving system of scanning sonar JP2057380 1980-02-22 JPS56118684A 1981-09-17 TAKAHASHI FUKUTAROU
PURPOSE:To form the echo signal with sufficient intensity in a simple constitution, by attenuating one of the signals received by the neighbouring vibrators by a specified amount, increasing the other by a specified amount, mixing the resultant outputs, shifting the phases in response to the arrangement of the vibrators, performing adding process, and correcting the receivied sensitivity. CONSTITUTION:One of the received signals from the neighbouring vibrators Vn... and V'n-1... which are sequentially switched by switches SW are attenuated by a ganged variable attenuator GATT from 100% to 50%, and the other is increased from 0% to 100%. Both signals are mixed and processed in mixers M1.... In this constitution, a plurality of vector signals whose magnitudes are always constant and phases are different are generated from the mixers M1.... The circuit becomes equivalent to a circuit wherein additional vibrators are arranged between the neighbouring vibrators. The outputs of these mixer M1... are processed by a mixer MIX-2 via phase shifters FS. Therefore, the received sensitivity is actually corrected by a simple constitution and sufficiently intense echo signal can be generated.
