Radartehnoloogias, often simply referred to as radar, is a detection system that uses radio waves to determine the range, angle, or velocity of objects. It is an acronym for Radio Detection and Ranging. Radar works by transmitting radio waves and then detecting the reflections of those waves that bounce off an object. The time it takes for the reflected waves to return to the radar antenna, along with the frequency shift of the returning waves, can be used to calculate the object's distance and speed.

The fundamental components of a radar system include a transmitter, a receiver, and a transmitting/receiving antenna. The transmitter generates electromagnetic waves, which are then directed by the antenna towards the target. When these waves encounter an object, they are reflected back towards the antenna. The receiver captures these returning echoes, and sophisticated signal processing techniques are employed to interpret the data. Different types of radar exist, including pulse radar, which sends out short bursts of energy, and continuous-wave (CW) radar, which transmits a continuous signal. Doppler radar is a specific type that utilizes the Doppler effect to measure the velocity of objects.

Radar technology has a wide range of applications. In meteorology, it is crucial for tracking weather patterns, detecting storms, and forecasting precipitation. The aviation industry relies heavily on radar for air traffic control, navigation, and surveillance. Military applications include target acquisition, missile guidance, and early warning systems. Maritime radar is essential for navigation, collision avoidance, and search and rescue operations. Furthermore, radar finds use in automotive systems for adaptive cruise control and blind-spot detection, as well as in scientific research for tasks like mapping the Earth's surface and studying celestial bodies. The continuous development of radar technology aims to improve resolution, range, and the ability to operate in challenging environments.
