How is reflectivity measured radar?
A radar signal is an electromagnetic (EM) wave, and as such will travel at the speed of light in the atmosphere. If part of the space has different EM properties, then some of the wave will be reflected from that region. Solid objects are t... Read More »

What does radar measures?
It measures the time it takes for a radio signal of a particular frequency to travel to a target and back. It also measures the strength of the signal when it returns. Based on the travel time of the signal, the radar can measure the distan... Read More »

How Does a Radar Gun Measure Speed?
Radar Radar is a system which uses radio waves to find objects which are both stationary and in motion. The word radar is an abbreviation of "radio detection and ranging." Like many technologies, radar systems used to be huge, taking up ent... Read More »
