This is a some-what loaded question. Advantages compared to what? My assumption is that you are comparing CW to Pulsed Radar systems. From there the question needs further defined by application. Differences between Pulsed and CW radar could be a book.
Generally Continuous Wave Radar references a radar system in which the transmitter is never turned off. The target illuminating, radio frequency emitter power is non-stop and unbroken. Isolation between the transmitter and receiver has to be specially considered during design. CW Radars have the advantage of not having blind range. They also have they also have the advantage of not missing targets that are in there field of view for less time than the Pulse Recurrent Time (PRT) of the radar.

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.
Cw radar vs cw radar?
CW in reference to radar usually means Continuous Wave. (CW Radar = Continuous Wave Radar) I don't think that it is usually referred to in a case sensitive way. You will need to explain the context better. Continuous Wave Radar references a radar system in which the transmitter is never turned off. The target illuminating, radio frequency emitter power is non-stop and unbroken. Isolation between the transmitter and receiver has to be specially considered during design.
Why frequency modulation is prefer in FM cw radars?
Because if they didn't use frequency modulation it wouldn't be called an "FM" CW Radar...
What are differences between CW radar and pulse 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 difference between pulse radar and CW radar?
CW or continuous-wave radar cannot determine range due to the lack of a listening period where the radar signal is silent. Pulse radar has a silent listening period (hence the name pulse radar). Therefore it can determine the range of the object causing the return by counting the elapsed time between transmission and receipt of the echo. The above is not quite correct, Continuous Wave Radar and Pulsed Radar differ by there relationship between the Pulse Width (tau) and the scene size (Swath). CW Radar's determine range by Frequency Modulation (FM) ranging this means that they ramp the RF frequency within the pulse during the transmission and are known as FMCW Radar. Pulsed Radar on the other hand use the pulse timing but can also use the FM Ranging trick to enhanced there signal to noise and reduce there probability of interference or detection/interception. CW radar can deduce range by delaying the transmit signal and mixing it with the receive such that it becomes a homodyne receiver and in such cases it is usual to ramp the RF and perhaps use two aerials rather then just one with a duplexer switch like in a Pulse radar system. Edit- hmm i feel the above answer is bit too complex... i don't think typical person would go as far as concerning FM or Pulse Delay Ranging here's my Answer DIFFERENCES BETWEEN PULSE AND CW RADAR Basis -Transmission Pulse RADAR puts delay between transmitting and receiving periods so the time between transmitted pulse and received pulse is different While CW RADAR, Transmit continuously -Antennas Pulse RADAR may use same antenna for Receiving and Transmitting , when transmitting the receiver is "blanked" and while Receiving the receiver is Activated and transmitter is blanked .. this is done by a device called "Duplexer" CW RADAR typically used 2 Antennas, one for transmit another one to Receive since there are no delay to receive as what usually seen in pulse RADAR -Ranging technique Pulse RADAR may use "Pulse Delay Ranging" to provide Range measurements , Frequency Modulation Ranging may also possible , especially for pulse RADAR that transmit many pulses and have very shot time to "listen" example is FMICW (Frequency Modulated Interrupted Continuous Wave RADAR) While CW RADAR provides Range by means of Doppler based Ranging (FM Ranging)
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 advantages of radar?
Radar does not require a light source and it has its own illumination source and can be used at night, Radar can be used so see though weather or indeed to track and monitor weather. Radar provides range and direction to provide a plan view of an area
