The main advantage of RADAR, is that it provide superior penetration capability through any type of weather condition, and can be used in the day or night time. Radar uses electromagnetic wave that does not require a medium like Sonar (that uses water) so can be used in space and air. Radar can be long range and the wave propagate at the speed of light rather then sound (like with sonar). It is less susceptible to weather conditions compared with Lasers.And be used at night unlike passive cameras. It does not require target cooperation to emit any signals or emission.
EDIT- Simple fix in spelling and slight expansion to previous answer
Radar!
As far as I know, radar was invented by a Hungarian scientist named Zoltan Bay. That radar was first used in World War II by the British troops.
No world is a stage, and you cannot detect a helicopter unless you have the radar station (radar alone is not sufficient)
Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.
tracking radar
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.
It is used to detect planes in a wide variation of ranges
radar, enigma, and superior number of aricraft
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
radar communication isfaster and has less attenuation(loss of signals).it is wireless so more preferred over other modes of communication
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.
If we use only stationery target indication radar then we can't recognize targets are whether moving or stationary. next time previous will be indicated as new object appear at another place when we don't use MTI with 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
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.
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.
It uses Squint Phenomena. Target abd clutter will be hit by two beams seperately. By this radar echoes will be added up whereas clutter which has Radar Cross Section Fluctuations will average. By this desired targets will be obtained with reduced fluctuations.
A radar mast is a high platform to mount a radar antenna such as the radar has an unobstructed view.
