🔬 How Radar Guns Work: The Science Behind Speed Detection
Radar guns use advanced physics — specifically the Doppler Effect — to
measure speed accurately. Whether you're training athletes, enforcing speed limits, or conducting
research, radar gun technology plays a critical role in real-time velocity tracking.
⚡ What Is the Doppler Effect and How Does It Help Measure Speed?
Radar guns emit radio waves that reflect off moving objects. The frequency of the returning signal
changes based on the object's motion — a phenomenon known as the Doppler shift. By
analyzing this shift, radar devices can instantly calculate the object’s speed.
📚 A Brief History of Radar Gun Technology
Radar was developed in the 1930s and 1940s for military applications during World War
II. By the 1970s, sports and law enforcement adopted radar guns for speed tracking —
starting with Major League Baseball to monitor pitch velocity.
