What are the advantages of radar range over radar bearing?
Radar range is the distance of the object from the radar. Radar bearing is the direction of the object in relation to the radar. As radar is primarily used for ranging, the range information may be more important than the bearing.
What is the history of germanium diode?
Germanium point contact diodes were first created and used during World War 2 as detectors in microwave RADAR systems, as the vacuum tubes available at that time did not operate at microwave frequencies. Shortly after World War 2 germanium junction diodes were created.
Are x-rays used for radar?
No. Radar use electromagnetic radiation of a much longer wavelength
What does dopler radar do?
A Doppler radar is a specialized radar that makes use of the Doppler effect to produce velocity data about objects at a distance. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the returned signal has been altered by the object's motion. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Doppler radars are used in aviation, sounding satellites, meteorology, police speed guns,[1], radiology, and bistatic radar (surface to air missile).
What can Doppler radar show?
Doppler radar is commonly used to detect precipitation and how much is coming down and can also be used to measure wind speed.
How does the wavelength of the waves used in microwaves ovens compare with the wavelength of waves used for radar?
Inches (microwave) vs. Feet (Radar).
How does the wavelength of waves used in the microwave ovens compare with the wavelength of waves used for radar?
The wavelength used in the microwave oven is about 12 centimeters. (rounded) In the early days, there were radar systems that used wavelengths longer than that, but there haven't been any for several decades now.
Microwave and radar question papers of 5th semister vtu university?

What are the uses of TRAPATT diodes in microwave communications?
1.They are used in microwave beacon. 2.They are used in low power Doppler radar as local oscillator . 3.They are used in landing system.
What are the names of three inventions that use radar technology?
microwave, radar system and um ducks
How can you define a radar?
measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects
Inventor of microwave?
Percy Spencer invented the very first microwave oven, called the 'Radarange', after World War II. He used radar technology developed during the war.
What was invented during a research project involving radar?
Microwave
Remote sensing devices used to study the ocean floor?
Echo sounder, seismic profiler, magnetometer, microwave radar.
What type of rectifier used in radar?
the usual semiconductor rectifier used in the microwave band is a gunn diode. Vacuum tube diodes are sometimes used too.
What is the difference between a microwave and a radar range microwave?
Radar Range is a brand name. All microwaves are the same thing. It is like Mr. Coffee coffee maker, just a name.
