Abstract
A method to confuse a police radar by moving a multiplicity of radar reflector antennas in the field of view of the radar. The moving radar reflector antennas present continuously changing doppler velocities to the police radar. The radar reflectors can be any of several reflective antennas such as dipoles, Yagies, horns, etc. The continuously changing doppler velocities are generated by mounting the radar reflector antennas on a moving disk. The moving disk is driven by an electric motor or by the wind. The radar reflector antennas can also be mounted on the rim or in the tread of a vehicle's tires.
