What type of electromagnetic wave is used for radar?
It is microwaves that are used for radar. They are high frequency, short wavelength electromagnetic waves, and a number of different frequency ranges of these microwaves are used depending on the application. A link is provided to the Wikipedia article on radar and the different bands or ranges of frequencies that are used and their applications.
What do radar engineers make?
A radar engineer works with radar. They have design, develop, install, and test a radar.
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.
Defferential cw radar and pulsed radar?
CW Radar or Continues Wave Radar uses a constant transmission and is usually used for angle only tracking and can be combined with a second emission that is pulses or swept to deuce range using and separate antenna (or on a time schedule in some cases). The CW part of a CW Radar reference to the transition duty Ratio and because Dead and Listen time are over lapped they normally have two antennas. FM CW Radar or Frequency Modulated Continues Wave Radar, is similar to the CW set up but the Carrier Radio Frequency is swept, when processed this data can produce range data. Again the Dead and Listen time our overlapped and it is normal for separated antenna to be used. The Frequency sweep is repeated in successive management ion different angles Pulsed Radar Transmits a short pulse rather then continuously like the FMCW Radar or CW Radar and has a short Dead time and long listen time During the dead time when the transmission pulse is emitted the receiver is blanked to protect it, After the pulse has completed transmission the receiver is opened to receive the returns. This means that the receiver and transmission times are mutually exclusive and therefore the same antenna can used for both jobs. As the pulse is short the transmission peak power maybe higher then the CW Power but is present for less time. A Hybrid Radar is ICW or Interrupted Continues Wave (some times called Interrupted Carrier Wave) which is really a pulse radar with a high duty cycle.
Is fmcw radar a doppler radar?
An FMCW radar may make use of Doppler, but it doesn't necessarily.
Does radar have a long a or short?
The word radar has a long A sound for the first A, and an umlaut A (ahr) for the second A.
Does radar have a short a or long a?
The word radar has a long A sound for the first A, and an umlaut A (ahr) for the second A.
What is a palindrome for a method of tracking ships and planes?
That is radar, which is short for radio direction and ranging.
What is the airport code for Point Lonely Short Range Radar Site?
The airport code for Point Lonely Short Range Radar Site is LNI.
Radar waves are too long or too short to be seen?
Radar waves are too long to be seen.
Does radar have a short or long vowel sound?
The word radar has a long A sound for the first A, and an umlaut A (ahr) for the second A.
Does Radar have a long or short a vowel sound?
The first A in radar has a long A (ay) sound, the second an umlaut A sound (ahr).
Are radar waves too short to see?
no they are too long
Are radar waves too long or too short to be seen?
Too Long.
Do tornadoes go off the radar?
Sometimes tornadoes can evade radar detection. This most often happens if the tornado is short lived, and thus is missed as the radar beam rotates, or occurs far away from the radar. Fortunately this occurs less often with strong tornadoes.
What is the main advantages of Doppler radar over conventional weather radar?
Conventional radar works by transmitting short pulses of electromagnetic energy. A small fraction of the waves that are sent out is scattered by a storm and returned to the radar, the strength of the returning signal indicates rainfall intensity and the time difference between the transmission and return of the signal indicates the distance of the storm. Doppler radar not only performs the same tasks as convention radar but also has the ability to detect motion patterns associated with tornadoes and severe thunderstorms, the conventional radar cannot.
