A bat can tell how big an insect is based on the intensity of the echo. A smaller object will reflect less of the sound wave, and so will produce a less intense echo.The bat can sense in which direction the insect is moving based on the pitch of the echo. If the insect is moving away from the bat, the returning echo will have a lower pitch than the original sound, while the echo from an insect moving toward the bat will have a higher pitch. This difference is due to the Doppler effect
Bats use the Doppler effect by emitting high-frequency sound waves while flying. When these sound waves bounce off objects in their path, the frequency of the returning echo changes based on the object's motion relative to the bat. Bats detect these changes in frequency to gauge the distance, speed, and direction of objects in their surroundings.
The Doppler effect is evident when a police car siren changes pitch as it approaches and then passes you.

The Doppler Effect was named after Austrian physicist Christian Doppler, who first described it in 1842.
The Doppler effect allows us to use the spectrum to study a source's motion. This effect causes a shift in the wavelengths of light emitted by a moving source, which can be detected and used to determine the direction and speed of the source's motion relative to the observer.
The change in frequency of a sound due to motion of the source is called the Doppler effect. If the source is moving towards the observer, the frequency of the sound appears higher (blueshifted), while if the source is moving away, the frequency appears lower (redshifted). This effect is commonly experienced with passing vehicles and sirens.

The Doppler effect proves that sound travels in waves.
The Doppler effect is the change in frequency of a sound wave. The Doppler effect causes a siren or engine to have a higher pitch when it is approaching than it does when it is receding.
Bats emit high-frequency sound waves through echolocation. When these sound waves bounce off objects and return to the bat, the Doppler effect helps the bat determine the speed and direction of the object. This allows the bat to locate prey in the dark by sensing the changes in frequency of the returning echoes.
The Doppler effect was discovered by Austrian physicist Christian Doppler in 1842. He observed that the frequency of sound waves changes when the source of the sound is in motion relative to the observer.
