Device and method for transceiving ultrasonic wave

An ultrasonic wave transceiving device, comprising:

• a transmitter configured to transmit a plurality of first detection data ultrasonic signals as one group;
• a receiver configured to receive echo signals of the first detection data ultrasonic signals;
• an information generator configured to generate first information pertaining to an object based on each of the echo signals of the group of the first detection data ultrasonic signals;
• and
• an additional information generator configured to generate additional information pertaining to characteristics of the object by using echo signals of the first detection data ultrasonic signals that are adjacent to each other in a time axis.

A method of transceiving ultrasonic waves, comprising:

• transmitting at least one kind of first detection data ultrasonic signal and first and second kinds of second detection data ultrasonic signal, such that during a first transmission period the transmitter transmits the at least one kind of first detection data ultrasonic signal and the first kind of second detection data ultrasonic signal without transmitting the second kind of second detection data ultrasonic signal, and during a second transmission period, which is adjacent to the first transmission period in a time axis, the transmitter transmits the at least one kind of first detection data ultrasonic signal and the second kind of second detection data ultrasonic signal without transmitting the first kind of second detection data ultrasonic signal so that the at least one kind of first detection data ultrasonic signal in the second transmission period is between the first kind of second detection data ultrasonic signal in the first transmission period and the second kind of the second detection data ultrasonic signal in the second transmission period along the time axis;
• receiving echo signals of the first and second detection data ultrasonic signals;
• generating first information based on an echo signal of the first detection data ultrasonic signal;
• and
• generating second information, relating to the first information, based on echo signals of the first and second kinds of the second detection data ultrasonic signal transmitted during the first transmission period and the second transmission period, respectively.
