There is no "advantage and disadvantage of radar range over radar bearing" because they're two separate measurements.
You take both measurements with a radar. Your first measurement listed was radar range. It's pretty simple to measure. Your radar puts out a pulse of energy. That energy flies through free air at 300,000 kilometers per second--it's a little less but that number will work. It has to hit the target and come back, so the speed of radar is actually 150,000 km/sec. If the pulse comes back 1/10,000 of a second after it went out, the target is 15 km away.
Radar bearing is even simpler: you index your antenna to true north. If your antenna is turning and it gets a reflection when your antenna is on a 40-degree azimuth, and the target is 10 km from where you are, you can pinpoint the guy pretty easily.
There are a few other tests you can do with a radar, like altitude (this is done with a radar that scans up and down rather than side to side, used in conjunction with a distance-measuring radar - if you know the angle from you to the plane you're trying to shoot down and its distance from you, you can calculate its altitude) and speed. Measuring speed is done with a radar with a fixed antenna, and it uses the Doppler principle. You send out a radar beam at a known frequency. It reflects off the target, changing frequency as it does - the frequency increases if the target is moving toward the radar, and decreases if the target is moving away from it. (This is how police radar works, and a million cops can't be wrong.) When the beam returns to the radar, they mix the returned signal with the signal coming off the oscillator. They will "beat" together and produce a signal with the difference frequency - if you send out a 10 GHz signal and get one back that is 1200 Hertz lower, mixing the two signals out-of-phase produces a 1200 Hertz signal. They know the number of Hertz the signal will shift for each mile or kilometer per hour; divide the difference signal by the difference-per-unit of speed, subtract the legal speed in the area, and you get the amount of trouble you're in.
You can also guide missiles with radar. This takes two radars. One of them is a target tracking radar. The other is on a different frequency and its antenna is steered by the target tracker so it illuminates the thing you're trying to kill. The missile senses that second radar's frequency and rides in on the radar beam.
And finally is the Phased Array Radar. Phased array radars consist of a panel containing thousands of radar transceivers arranged in a grid, that are switched and interpreted by a computer. You can install multiple panels in your system; the AEGIS radar system the US Navy uses has four panels in it. The advantage of a phased array is it can do everything all the other radar types can do, at the same time and on multiple targets. The disadvantages are that it's expensive, it's big and it requires a huge amount of power to make this work - the AEGIS system has a maximum power output off all four arrays of 6 megawatts. (This also introduces a workplace safety issue; an antenna emitting 1.5 megawatts of microwave energy will cook - literally cook, just like a microwave oven - anything within ten feet of it. Crewmen on AEGIS warships have to pick up the dead seagulls off the deck after the radar is used; if a bird flies in front of one of those arrays, it gets killed.) The advantages - being able to track altitude, speed and direction on every plane in the sky, and guide missiles on the hostiles, all at the same time on the same screen - so outweigh the disadvantages that designers will use phased arrays any time they can.

Why FMCW radar has better range resolution than CW radar?
FM CW radar sweeps the Radio Frequency over time. Time in Radar equates to range and results in a high spectral density at every range. CW radar has a much lower spectral density and does not code range with frequency in the same way.
How to increase radar range?
The maximum distance at which a radar set is ordinarily effective in detecting objects can be increase by lowering the pulse frequency, raising the peak power of the transmitter, narrow the beam with and increasing the pulse duration
Do police know if you are using a radar detector?
AnswerAll modern radar detectors use a local oscillator (LO). The local oscillator is part of the radar detector's superheterodyne circuitry which greatly boosts the radar detector's performance. Radio (actually microwave) emissions from a radar detector's local oscillator are readily detected by various types of radar detector detectors (RDDs) such as VG-2 and the Spectre. Spectre RDDs are in widespread use throughout the state of Virginia where radar detector usage is illegal. Although radar detectors at present are completely legal to use in all states except VA and Washington DC, the Texas DSP is known to use Spectres to nab unsuspecting motorists who use radar detectors. Several radar detector manufacturers have made strides during the past few years to greatly reduce the LO leakage from their products. This greatly reduces the range at which the Spectre RDD can detect these newer radar detector models. And, at present, there are three specific radar detector models which have virtually zero LO leakage. This makes these three radar detector models completely immune to detection by VG-2, by the Spectre, any other present technology, or any new technology which possibly could be developed during the next 5 years or so.

The biome found in Canada and populated with cone-bearing trees such as pine spruce and fir is the .?
The biome found in Canada that is populated with cone-bearing trees such as pine, spruce, and fir is the boreal forest, also known as the taiga. This biome is characterized by its cold climate, significant snowfall, and long winters, supporting a diverse range of wildlife and plant species. The boreal forest plays a crucial role in carbon storage and is one of the largest biomes in the world.
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 type of radar indicator uses a polar coordinate display to depict the range and bearing to targets?
PPI (plan position indicator).

FM CW radar sweeps the Radio Frequency over time. Time in Radar equates to range and results in a high spectral density at every range. CW radar has a much lower spectral density and does not code range with frequency in the same way.
Advantage and disadvantage of range?
The advantage of range in a set of data is that it provides a simple measure of the spread or dispersion of the values. It is easy to calculate by subtracting the minimum value from the maximum value. However, the disadvantage of range is that it is heavily influenced by outliers, as it only considers the two extreme values and may not accurately represent the variability of the entire dataset. For a more robust measure of dispersion, other statistical measures such as standard deviation or interquartile range may be more appropriate.
Advantage and disadvantage of petrol enines?
They're relatively light weight, and they have a concentrated fuel source. They have a narrow speed range of maximum efficiency, and they spew fumes.
What is a typical radar operating frequency?
Typical radar operates in the 50 to 330 megahertz bands. However, long range radar uses ultra high frequencies in the 300 to 1,000 megahertz range.
What amplitude and frequency does a radar waves have?
Frequency is above 1 GHz or so for radar. General amplitude of waves put out by a radar gun is what I was trying to find when I stumbled across this. I imagine its in the mV or lower range though

The airport code for Point Lonely Short Range Radar Site is LNI.
What are the components of a radar?
The main components of a radar system include a transmitter, which generates electromagnetic signals, a receiver, which captures the signals reflected off targets, an antenna, which radiates the signals and collects the echoes, and a signal processor, which analyzes the received data to detect targets and extract information such as range, bearing, and velocity.
What is one advantage and one disadvantage of alkyne?
One advantage of alkynes is their ability to undergo addition reactions to form a wide range of organic molecules. One disadvantage is that alkynes are highly reactive and can pose safety hazards due to their tendency to form explosive mixtures with air.
