How does Pulse Radar calculate the speed of an object?

Pulse Radar calculates the speed of an object by analyzing the frequency change of the reflected radar wave, a concept known as the Doppler effect. When the radar wave is transmitted towards a moving object, the wave reflects back with a frequency shift that corresponds to the object's speed relative to the radar system. If the object is moving towards the radar, the frequency increases; if it's moving away, the frequency decreases. By measuring this shift in frequency, the radar system can accurately determine the speed of the object. This method is fundamentally linked to the wave nature of the radar signals used, making it a direct and effective means of speed measurement in various applications, including law enforcement and traffic monitoring.

Other methods, like measuring weight or using satellite systems, do not provide the direct information necessary for speed calculation in the way that frequency analysis does.
