Radar (which in English is an abbreviation of Radio Detection and Ranging, which means radio detection and ranging) is an electromagnetic wave system that is useful for detecting, measuring distances and creating maps of objects such as airplanes, various motorized vehicles and weather information ( Rain).
The concept of radar is to measure the distance from the sensor to the target. This distance measure is obtained by measuring the time required for electromagnetic waves to propagate from the sensor to the target and back to the sensor.
In the field of shipping, radar is used to regulate ship travel routes so that each ship can travel and pass in its own lane and not collide with each other, even in unfavorable weather, for example foggy weather.
