If you are interested in military or aviation technology, you see one piece of equipment mentioned time and time again. Radar (short for Radio Detection And Ranging) is a way of locating objects and telling important information such as the direction in which those objects are traveling, how far away they are from a given point and how fast the object is traveling. The monopulse comparator is an important component of modern radar systems and has done much to make these systems more reliable and accurate.
Police officers routine use radar guns to determine whether vehicles are speeding. The signal will bounce out of a hand held device (known as a gun), bounce off of the targeted vehicle, and return in such a way that the officer can tell how fast that vehicle is going. The officer can then decide whether or not any traffic laws have been broken and whether a vehicle should be ticketed.
Anyone who has seen a weather forecast has taken advantage of the information that radar can give us. Meteorologists will use the information given to them by Doppler radar to track changes in weather systems. It can help alert us to the formation of storm fronts which may develop from thunderstorms to tornadoes or hurricanes.
Radar is also used in marine environments. Ships can use it to detect other vessels that may be occupying the same area of water and can also use it to determine where they are located. This is done by bouncing signals off of known reference points such as buoys or, if close enough, the shoreline as well.
A radar system is made up of a transmitter, waveguide, duplexer, receiver and a display processor. The transmitter generates the radio frequency which will be used to detect objects. There is a waveguide that is used to connect the transmitter with an antenna that will send the radio frequency out into the environment. A duplexer is then used to switch the antenna from transmitting to receiving and the resulting signal is captured by the receiver and displayed on the display processor.
Jamming was an issue in the past but it is not as much of a problem with the modern monopulse systems that are being used. Because these systems rely on radio frequencies to detect objects, if a radio signal of the same frequency was directed at the radar system itself it tended to interfere with the signal and the system could not produce an accurate image. The monopulse system, because of the way it is set up, makes jamming much more difficult.
With modern systems, a single beam is emitted that is then split into two sections. They are directed in the same general direction but because they are positioned in slightly different ways it is possible to compare the returning signals to make sure that the results are accurate. A comparator is the device used to combine the signals into the single cohesive image that the radar operator will interpret.
There are several different types of these devices. The type that you choose will depend on exactly which kind of radar system you have set up. You can find comparators online although generally only on specialty websites that offer other radar equipment as well.
