radar physics

Radar physics involves sending out radio waves that travel through the air at the speed of light. When these waves hit an object, they reflect back to the radar receiver. By measuring the time it takes for the echoes to return, the system calculates the distance to the object. Additionally, analyzing the change in frequency (Doppler shift) of the reflected waves reveals the object's speed and direction. Radar is used for navigation, weather detection, and tracking objects, relying on the principles of electromagnetic wave reflection, timing, and frequency analysis to accurately detect and locate targets.
