What You Need To Know About The Monopulse Comparator And Radars In General

By Elaine Guthrie


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.

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.

Meteorologists have also started using these systems to monitor the weather and create forecasts. They can be very helpful if a severe weather system is expected. Radar can be used to determine how large or severe a storm such as a hurricane or a tornado is. Other types of storms such as blizzards and thunderstorms can also be mapped using these systems.

While many people think that these systems can just be used on land, this is not true. Marine radar will bounce signals off of nearby objects. This shows a ship where it is (by detecting the shoreline or marine buoys) or whether there are other ships in the same area.

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.

In the beginning, the way the signal was generated and processed meant that radar systems were not as reliable or accurate as they are today. They could be jammed easily. This involves directing the same radio frequency at the system in order to give an inaccurate picture of what is going on in the area. With the invention of the monopulse system, this was corrected and new systems are much more accurate.

A comparator allows for a radar beam to split into multiple segments. Originally the beam was split into two sections although now there are comparators which allow for a beam to be split into four sections instead. When the beams are compared, the slight differences in position between each of the beams allows the radar system to more precisely locate where a particular object it is or how fast it is moving.

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.
