wherein t represents the time from transmission to reception of the ultrasonic wave,

represents the product of the actual propagation speed of the ultrasonic wave and the propagation time from the transmitting end to the obstacle, which can be represented by S;

v₀represents the initial transmission speed of the ultrasonic wave, and T represents the temperature of the current propagation environment.
