What types of targets can radar systems detect?

Radar systems are designed to detect a wide variety of targets, which include both moving and stationary objects. This capability stems from the fundamental operating principles of radar, which rely on the transmission of electromagnetic waves. When these waves encounter an object, they can be reflected back to the radar system, allowing it to identify the presence and position of the target.

For stationary objects, radar can detect them as long as they create a sufficient radar cross-section – that is, they reflect enough of the radar signal back to the receiver. On the other hand, moving objects are also detectable due to the Doppler effect; the frequency of the returned signal changes based on the relative motion between the radar and the target. This enables the radar to not only locate the object but also provide information about its speed and direction.

The versatility of radar systems means that they are employed in a variety of applications, such as air traffic control, weather monitoring, and military contexts, where detecting both types of targets is crucial for effective operation. This makes the ability to detect both moving and stationary targets a fundamental characteristic of radar technology.
