In what ways have humans mimicked bats and made progress?

Radar, ultrasound from the bat's mouth.

1. What do people learn from bats?

People took inspiration from bats and invented radar.

Bats mainly use ultrasonic echolocation signals to search for food, detect distance, determine targets, avoid obstacles and avoid predators, etc.

2. How do bats find their way?

It is the use of eyes and ears to find the way.

People invented radar based on bats. The secret of a bat's ability to fly at night is that it makes a sound from its mouth as it flies. This sound is called ultrasound, and it is inaudible to the human ear, but it can be heard by the bat ear.

The ultrasonic waves move forward like waves, and when they encounter obstacles, they reflect back and reach the ears of bats, which immediately change the direction of flight.

Bats are good at flying in the air, and can do a variety of "aerobats" such as circular turns, sudden braking, and rapid changes in flight speed. Scientists imitated the way bats found their way and equipped the plane with radar. The radar emits radio waves through the antenna, and when the radio waves encounter obstacles, they are reflected back and displayed on the phosphor screen.

From the fluorescent screen of the radar, the pilot can see whether there are any obstacles ahead, so the plane is very safe to fly at night.

Radar was invented.

Radar was invented based on the fact that bats can fly at night without using their eyes, and the bat can detect any obstacle that blocks it with ultrasound waves emitted by its ears and mouth, so that the exact location of these obstacles is displayed in the bat's brain, and the bat will not hit any obstacles. But on the contrary, if you plug the bat's ears and mouth, it will stumble like a headless fly. Radar is also the principle of bats emitting ultrasound waves, and they detect obstacles through ultrasound waves!

According to the principle of the bat ultrasound locator, people also imitated the "pathfinder" for the blind. This pathfinder is equipped with an ultrasonic emitter that a blind person can carry to spot people on electric poles, steps, bridges, etc. Today, "ultrasound glasses" with a similar effect have also been made.

radar and ultrasonic flaw detection, ultrasonic positioning, etc.

According to the main content of this text, scientists have uncovered the reason why bats can fly at night through repeated experiments, and have been inspired by it to install radar on airplanes and solve the problem of safe flight of airplanes at night

3. Why can an aircraft fly safely with radar?

radar); Taking a cue from the fish, he invented (the submarine.

From (birds. Inspired by the body, he invented (the glider).

People took inspiration from bats and invented radar. The radar emits electromagnetic waves to irradiate the target, and receives the callback to obtain information such as the distance, direction, and altitude from the target to the launch point.

Humans studied bats and invented radar.

The bat got a kind of thing called radar from the plane is the bat is used to cooperate with the mouth, and there is a kind of ultrasonic sound from the mouth The bat is quite cheap The bat ears can hear it and he can change the direction.
