How The Monopulse Comparator Has Improved Modern Radar Systems


by Elaine Guthrie


Fans of military technology may be quite familiar with radar technology. Individuals who enjoy air or marine travel have also benefited from this technology as well. Radar systems have changed quite a bit since the early days and one major change is the switch to a monopulse system. A monopulse comparator is a part of this system that has greatly increased the accuracy of modern systems. Here is what you need to know about these devices and how they have improved radar systems in general.

Radar systems were first developed and used by the military. Various countries found it very helpful to be able to detect approaching objects, find out how fast they were moving and what direction they were moving in. It allowed them to detect potential incoming attacks while paying less attention to non-hostile objects or aircraft. Now these systems are used by many different groups and organizations.

Weather forecasting also uses this type of system. It can track storm fronts, give information on where a storm is or how severe it is, and allows meteorologists to let us know important weather data. It can be used for tornadoes, hurricanes, blizzards and thunderstorms as well. Many weather broadcasts will display the results of Doppler radar as part of the broadcast so viewers can see the data for themselves.

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.

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.

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.

If you are interested in taking a closer look at these items you will quickly learn that there are different types. Looking online will give you the most comprehensive information on the different variants available although you may find you will need to check out specialized websites in order to view them.
