making the RADAR sensor configurable as per the application and scope. Below are some modulation patterns used for different measurement purposes: Sawtooth modulation: Relatively large range (maximum ...

Finally, a physical embodiment of the Doppler effect radar is demonstrated with a pair of Vivaldi horn antennas and a copper sheet. We really like how [Shahriar] structures his video: theory ...

but the phenomena has far reaching applications since discovered by Christian Doppler in 1842. The basic principle measures the distance of vibrations from a static source. For example ...
