Abstract: PROBLEM TO BE SOLVED: To prevent a main lobe from flaring out even in a system with a characteristic such that frequency components at the ends of a transmitted pulse signal are attenuated. SOLUTION: A transmitting/receiving circuit part 2 in this ultrasonograph includes: an echo waveform memory 31 for storing ultrasonic echo signals Re; a convolver 41 for convoluting the ultrasonic echo signals Re; a rounding part 42 extracting high level components I from the convolution results Ca; an inverse convolver 43 which subjects the high level components I to inverse convolutions; a remainder filter 44 having a characteristic such that the transfer function of a system is used as a band stop filter; a level adjuster 32 for adjusting the signal level of a correction signal K obtained through the remainder filter 44; and an adder 33 for adding together the ultrasonic echo signal Re and the correction signal K after level adjustment.  Thus, since the received echo signal can be corrected to restore the components attenuated by the system characteristic, the signal becomes equivalent to unattenuated signals and a main lobe can be prevented from flaring out, so that a halo on a screen can be reduced.
