Depends on the method used.
In RADAR, they use the Doppler effect, coupled with specific band waves. the k( 20 - 40 GHz) range, the x range(8.0 - 12.0 GHz), and the Ka range(26.5 - 40 GHz). They also tend to use the IR range.
There is also the LADAR system. I was unable to find the wavelengths of the laser they use, but whats important is they use a focused pulse laser system that sends out about 100 pulses in 3/10ths of a second. This system does not use the Doppler effect, but some other more complex algorithms to calculate more than just speed.
What else can I help you with?
What kind of eiectromagnetic waves you can not detect with your eyes?
Everything except visible light (cosmic, X-rays, radio, infra-red, ultra-violet, etc.).
How do scientist detect heat waves?
Consider a blind person, he cannot see sun but he can tell if he is standing in sun or shade, how? Because he can feel infrared waves heating up his/her skin. Similarly there are certain substances that are sensitive to certain kind of waves, there can be an arrangement to detect these like a circuit to detect radio waves and so on.
What kind of waves are detected by ears?
Ears detect sound waves, which are mechanical vibrations that travel through a medium such as air, water, or solid materials. These waves cause the eardrum to vibrate, which is then translated into electrical signals by the inner ear and sent to the brain for processing and interpretation as sound.
What kind of waves are electromagnet waves?
They are transverse waves.
What kind of waves are electromagnetic waves classified as?
They are tranverse waves.
What kind of cases do federal courts not try?
speeding tickets
What kind of waves do humans see?
visible waves visible waves
What kind of waves are in radar detectors?
Radio waves.
What kind of waves is water waves?
Transverse wave
What kind of waves are all sound waves?
transverse
Which kind of waves are sound waves?
compressional waves they swerve up and down
What kind of waves create sound?
Sound waves are created by mechanical vibrations that travel through a medium, such as air or water. When an object vibrates, it causes nearby air molecules to also vibrate, creating areas of compression and rarefaction. Our ears can detect these vibrations and perceive them as sound.
