outdoor radar speed display speed sensor radar usa introduction
radar detector module used in roadway vehicle detect, connetct to cemera, for over speed vehicle photos taken.
The low-end stuff that we can get our hands on usually suffers from poor range, lack of sensitivity, and no way to characterize what the target is. But today we can use the good stuff that, until recently, was only available to military: radar. In this post we will discuss how radar works, commercially available small radar devices, and where to learn more to help make it easy to add radar to your next project. Reach out and sense something!
