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.

When was Under the Radar Over the Top created?
Under the Radar Over the Top was created on 2009-10-02.
What are the disadvantages of radar?
Time - Radar can take up to 2 seconds to lock onRadar has wide beam spread (50 ft diameter over 200 ft range)Cannot track if deceleration is greater than one mph/secondLarge targets close to radar can saturate receiverHand-held modulation can falsify readingsMore interference sources
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.
What is electronics and advantages and disadvantages of bassel filter?
A filter with a Bessel-type response has a phase response that is proportional to frequency over as wide a range of frequencies as possible. The idea is to simulate a delay line.
What is radar navigation?
"RADAR" is an acronym for RAdio Detection And Ranging, which is a broadcast beam and receiver, used primarily to detect the objects (such as aircraft) which are at a distance that cannot be observed visually. It is one of the applications of microwaves. Radar is used along with advanced transponder technology in air traffic control. Smaller radar units have been used to measure the speed of cars and trucks on highways, using the Doppler effect (frequency shift for moving objects), although these have mostly been replaced with laser devices using the same principle. Radar is based on the principle that the RF signal at a high frequency is reflected back by reflective objects, typically large objects made from metal, composites, or rubberized materials. The distance between the radar antenna and the target can be measured by the delay time (microseconds, millionths of a second) between the broadcast and detected return. The reflected signal is known as a 'radio echo'. The time taken by the signal to travel one nautical mile is 6.18 micro seconds, so it requires 12.36 microseconds to reach and return from an object one nautical mile away. The formula to determine the distance of the object 'S' is S=T/12.34 where 'T' is the time taken for the transmission and reception of the signal. --- Radar is an acronym for RAdio Detection and Ranging. It uses RF transmission (radio frequency) in the microwave band to detect and range any detectable target within its range. It is an "active sensor" which emits RF waves that bounce off a target and are detected when the wave is received back. The time delay between transmission and detection produces its range given that the RF wave propagates at a uniform speed. Modern "stealth" aircraft use RF scattering, along with microwave-absorbing materials, to avoid detection by traditional radar. Some advanced planes have radar reflection signatures so low that they are less than those of small birds.
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.
What are the advantages of radar communication?
radar communication isfaster and has less attenuation(loss of signals).it is wireless so more preferred over other modes of communication
Who sells a Passport radar detector?
Escort Radar sells passport radar detectors and there is a small fee to pay. They can be bought over the telephone or online. These are very easy to get your hands on and they sells a wide range of radars.
What advantages do laser guns have over radar guns?
Laser speed guns can target ONE specific vehicle, where radar may read one of several vehicle. Laser is harder to detect in advance, and harder to jam than radar.
What are the advantages of a range oven?
The advantages of a range over, or a range cooker over any other kind of cooker appliances such as the microwave would be that it can bake things, it can cook things that require more time and doesn't simply just heat the foot.
What is the range of a radar?
Different models of Police Radar have different ranges... A top of the line Radar, generally used by Highway Patrol, has a Range varying from 3/4 of a mile to over 2 miles. Less expensive units are from 1/2 to 1 mile. However, most officers will "track" a target vehicle for several seconds before accepting a reading from the Radar, so the EFFECTIVE range is about 1/2 to 3/ 4 mile.
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.
What are the advantages using 3D Radar over 2D Radar?
The three Dimensional maps created a revolution in the field of navigation and medical and also in the engineering field. The advantage of 3D maps are that it can give the idea of all the dimensions and hence better designs can be created by looking at the 3d maps and the conventional maps were not that much informative compared to 3D maps are
When was Under the Radar Over the Top created?
Under the Radar Over the Top was created on 2009-10-02.
What is the advantages of the human eye over the camera?
The primary advantages are:Sensitivity range (we can see in much brighter and dimmer light situations)The processing done to the image by our brains
How far away can a police radar spot your speed?
Police radar can typically spot your speed from up to a few hundred feet away, depending on the model and conditions such as weather and line of sight. Advanced radar systems may have a longer range, but generally, they are effective within a few hundred meters.
What are some of the advantages of city apartments over hotels?
The main advantages of city apartments are that they are conveniently located, the range and availabilty of different complexes to choose from that will suit your needs better than a hotel.
