Why do bats emit pulses of ultrasound INSTEAD of continuous waves of ultrasound to navigate?

For the same reason that radar and sonar systems don't transmit continuously.
The information value of these systems comes from interpreting the echo, and
it's very difficult ... virtually impossible ... to receive a low-level signal at the same
frequency while you're transmitting.
That's also the reason why the protocol for the most effective human conversation
involves alternate periods of talking and buttoning it.

What medical technique used sound wave pulses and their reflections to map structures and organs inside the body?
Ultra Sound
What kind of pulses did Venus' topography has been mapped from space and earth?
wave pulses
What is the rainfall required for pulses?
Temperature: 200c to 250cRainfall: 50cm to 75cm
How does a laser measure distances?
A laser measures distances by sending out pulses, and measuring the time it takes for these pulses to bounce back. Lasers are efficient and great measurement tools.
What are dry peas used for?
dried peas are used as pulses and lentil
Why is ultrasound transmitted in pulses?

All waves consist of a continuous series of?
pulses
Analog computer works on the supply of?
electrical pulses but not continuous
What medical technique used sound wave pulses and their reflections to map structures and organs inside the body?
Ultra Sound
What is echlocation?
Echolocation is a type of radar bats use to fly blind. The bats send out pulses of super sonic sound and navigate by the speed of the pulses return from what they bounced ( echoed ) off.
What diagnostic technique creates images of deep body structures by recording the echoes of pulses of sound waves that are above the range of human hearing?
Ultrasound
What creates images of deep body structures by recording the echoes of pulses of sound waves that are above the range of human hearing?
You are refering to ultrasound imaging...Most commonly used in obsteric sonography, which is the imaging of babies within a mothers' womb**Actually the correct medical term for this definition is Ultrasonography. This is the term commonly known as ultrasound or diagnostic ultrasound.**

Why is analogue a series of pulses?
An analogue signal is not a series of pulses. An analogue signal is a continuous signal which is modulated (changed) in some way to carry information. Common modulations for analogue are Amplitude Modulation (AM), and Frequency Modulation, (FM). There are some others but are not needed here.
Why do bats emit short pulses of ultrasound?
Bats are mostly blind so they cry (kind of a screaming/screeching sound), and then they can see the sound waves either bounce off of something that is blocking their way, or just keep going straight in front of them. Then they know weather to turn or go straight.
What are the advantages of pulses?
pulses? like in the pulses you heart makes us hear?
What is a digital signal?
they are non continuous signals that consist of pulses or digits with dicrete levels or values (usually with value 0 or 1). In digital transmission, the singlas are converted to bindary code.
