    • PURPOSE:To facilitate the discrimination between a signal and noise and to enhance the discrimination capacity of a target, by uniformizing a reflected signal different in a peak level to display the same. CONSTITUTION:The sonic wave from a transmitter is reflected from a target to be received by a receiver 1 and converted to an electric signal. Subsequently, said electric signal is converted to a digital receiving signal by an A/D converter circuit 2 to be sent to the first operation circuit 3 and converted to a positive envelope detection signal. This signal V is sent to the first memory circuit 5 to be stored therein and, at the same time, also sent to an average value circuit 4. The circuit 4 calculates the average level -V of a definite period containing the reflected signal in the signal sent from the circuit 3 to send the same to the second memory circuit 6 and calculates the average level -N only of the noise of the definite period to send the same to the third memory circuit 7. These data stored in three memory circuits are sent to the second operation circuit 8 to perform operations shown by formulae I, II, III. The calculated sample data of the formula III is displayed on a display circuit 9 to make it possible to uniformize a reflected signal level.

    • PURPOSE:To enable the presence of always useful information during a sampling period, by automatically changing the delay time of a sea bottom reflected wave. CONSTITUTION:A sound wave is transmitted to the sea bottom at constant intervals from a transmitter 22 and, at the same time, a trigger signal is supplied to a delay circuit 25 from a transmission part 21 while delay output is supplied to a sample circuit 24 as a sampling start trigger signal. On the other hand, the reflected sound wave at the sea bottom is supplied to the sample circuit 24 through receiver 23 and sample output is supplied to an A/D converter 26, a data collecting circuit 27 and a sea bottom detecting circuit 28. When the reflected wave is detected, a sea bottom reflected wave time measuring circuit 29 is operated by said output and the calculated time data is sent to a comparator circuit 30 to be compared with the time of setting circuits 31, 32 while a command signal is imparted to the delay circuit 25 from the command circuit 33 by the compared output at the time of a predetermined state to perform the adjustment of the delay time.

    • PURPOSE:To display the signal of an object so as to be capable of easily discriminating the same from other signals, by a method wherein a timewise phase difference signal is converted to a phase difference signal to frequency and discriminating the phase difference signal to frequency equal to or less than predetermined frequency and equal to or more than a predetermined level from the other signal as the signal of the object. CONSTITUTION:The signal received by a first receiver 1 and the signal received by a second receiver 2 are sent to a correlation device 3 and receive correlation processing to calculate a phase difference signal phi. This phase difference signal phi is the function of the incident angle phi of a plane wave and sent to a memory 4 to be temporarily stored therein as a time series signal. In the memory 4, a time width T is made constant while a delivery range is timewise shifted by T and repeatedly sent to a Fourier transformer 5 which in turn performs frequency analysis at every time series signal of the time width T. The frequency spectrum 105 of the output of the Fourier transformer 5 is sent, to a threshold value judge device 6. The threshold value judging device 6 judges whether the sent signal frequency spectrum has a value equal to or less than certain frequency and equal to or more than a predetermined level and outputs said spectrum.
