Radar detects objects or targets by transmitting electromagnetic waves (usually radio waves or microwaves) from an antenna and receiving their reflections. These waves bounce off objects in their path and return to the radar system, where they are detected by a receiver. The radar system analyzes the time it takes for signals to return and their Doppler shift (change in frequency due to object movement) to determine the distance, direction, speed and other characteristics of detected targets.
The radar can detect a wide range of objects based on their size, shape, material composition and distance from the radar antenna, including aircraft, ships, vehicles, weather formations and even space debris.
A radar sensor, similar to a radar system, detects objects by transmitting electromagnetic waves and receiving their reflections. The term “radar sensor” is often used to describe a radar module or unit integrated into various systems or devices for specific applications.
For example, automotive radar sensors are used in advanced driver assistance systems (ADAS) and autonomous vehicles to detect nearby vehicles, pedestrians, and obstacles. These sensors operate similarly to traditional radar systems but are designed with specific features and capabilities tailored to their intended use, such as compact size, low power consumption, and specialized signal processing algorithms for detecting radars.

A radar detector is a device designed to detect the presence of radar signals emitted by police radar guns used for speed enforcement. These devices are used primarily by motorists to alert them when law enforcement officers are using radar to monitor vehicle speeds. Radar detectors work by scanning specific frequencies typically used by radar guns and issuing an audible or visual alert to the driver when such signals are detected.
Although radar detectors themselves do not directly detect radar signals from other sources (such as weather radars or aircraft radars), they are specifically tuned to detect frequencies used by police radar guns , helping drivers potentially adjust their speed and avoid speeding tickets
