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.
When you are out at sea it can be difficult to determine your location when visibility is poor. Using a radar system will allow a ship to bounce signals off of known reference points. Marine buoys and the shoreline can both be used as reference points for a ship. The same system is also used to scan around the vessel to detect the presence of other vessels. This can help avoid collisions between two or more ships.
There are several components that make up a radar system. The signal is generated by a transmitter. This is sent out to an antenna by a waveguide. A duplexer that is connected to the antenna switches the system from sending to receiving and the resulting signal is then captured by a receiver. The information is processed and sent to a display processor so that the radar operator can see a visual picture of what the system has picked up.
Jamming used to be a significant issue with early systems. While most people think of jamming as an enemy action, this is not always the case. Jamming simply refers to interference from radio waves of the same frequency as a particular radar system. It can obscure objects or give an inaccurate idea of how fast they are traveling or the direction in which they are moving.
Splitting a beam of radio frequency into several portions really improves accuracy. This is because the different sections of the beam can be compared to find out if the result are accurate. A monopulse system can compare up to four different sections of frequency and the operator will get an excellent idea of what is out there and how it is moving.
These tend to be very specialized items and may not be commonly available. There are websites that offer different versions of comparators. If you are purchasing this type of item, it is important to read the description carefully and ensure you are purchasing the right kind of comparator.
