A: Radar is an piece of equipment that require extreme hi frequency the wave are so small that wire does cannot control the emission so wave guides are used like rectangular pipes to guide the waves around with minimum losses. Radar even though is classified as electronics it boils down that physics are more necessary then understanding electronics

Applications of a circular waveguides?
attenuators and phaseshifters
Is Doppler radar used for finding hurricanes?
Yes, Doppler Radar can be used to find all storms!
How is radar used to predict measure weather?
Weather radar devices electronically convert the reflected radio waves into picture that show the location and intensity of precipitation and the speed of the wind.
Why can't radar be used to measure the distance to stars?
Radar can only be used for planets close to us in the solar system and the planet or object must be able to reflect the wave back. Radar cannot be used to measure the distance between Earth and the Sun because the sun doesn't reflect the radio waves back.
Can radar be used to detect the location and movement of precipitation?
Yes, and often is.
Why waveguides are used instead of antennas?
waveguides are used instead of coax because at the high microwave frequencies coax would radiate the signal right through its shield. waveguides do not replace antennas.
What is circular waveguide?
It is a waveguide that is circular. Circular waveguides have modes that are described in terms of Bessel functions instead of the sines/cosines used for rectangular waveguides. The disadvantage is that the two lowest modes have cutoff frequencies spaced by less than an octave. Circular waveguides are used for rotating joints, for example in radar. The H01 mode in circular waveguide was used as a low-loss mode for transmitting signals over distance, but this technique has been replaced by fibre-optic cables.
What are the types in waveguides?
3 types: 1.electromagentic waveguides 2.optical waveguides 3.acoustic waveguides
What are electromagnetic waveguides?
A waveguide is a metal tube that is used to carry radio frequency energy from one place to another. It is commonly used in microwave telecommunications and radar. A typical waveguide ifor 10,000 Megahertz is about 1" by 0.5 " rectangular cross-section. There are also circular and eliptical waveguides. The size of the guide depends on the frequency in use. The lower the frequency, the bigger the waveguide. I have seen a waveguide that you could walk around in for 100 Mhz. Once you get past about 1000Mhz, wire transmission lines become very inefficient, and waveguides are better.
Why microwave is not used in radar?
Microwave IS used in RADAR.
What are radar waves used for?
radar
Difference between coaxial cable and wave guide?
Waveguides are used at higher frequencies where their loss is lower than coaxial cable. Coaxial cable is used at lower frequencies where waveguides are too large and heavy. Lastly Coaxial cable is also used at higher frequencies where some flexibility is required.
What is a dopppler radar?
a radar used by meteorologists
Applications of a circular waveguides?
attenuators and phaseshifters
What kind of radar is used to record tornado data?
Usually Doppler radar is used.
What do radar balloons do?
This could mean:A radar attached to a balloonA balloon used by a radar for calibration
Im looking for a radar detector that detects the presence of a radar when it is being used?
That would be any radar detector. If you want to detect a radar that is not being used, you need to find a psychic.
