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.

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
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.
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.
The Advantages are that Hovercraft can fly, or more suitably, hover over water and land, can go over rough terrain and does not pollute as much as cars.
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.
radar communication isfaster and has less attenuation(loss of signals).it is wireless so more preferred over other modes of communication
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.
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.
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.
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.
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.
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

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
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.
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.
