El funcionamiento del radar se basa en un fenómeno físico denominado efecto Doppler y se refiere a la variación de la frecuencia que emite un emisor en movimiento. [...] Los radares de tráfico mandan una señal al coche que pasa y reciben una señal rebotada. En función de las diferencias de la frecuencia de la señal rebotada en el coche que pasa se puede calcular la velocidad.
