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.
Claims20
A method to thwart an interrogating doppler radar from detecting the speed of a vehicle comprising the steps of:
- mounting a plurality of passive radar reflector antennas on a base, said plurality of passive radar reflector antennas being disposed around a center point of said base;
- rotatably mounting said base to the vehicle;
- and
- rotating said base about said center point in a field of view of the interrogating doppler radar.
A doppler radar jammer for thwarting an interrogating doppler radar from detecting the speed of a vehicle comprising:
- a base rotatably mounted to the vehicle;
- a plurality of passive radar reflector antennas located in a field of view of an interrogating doppler radar and mounted on and disposed around a center point of said base;
- and
- a means to rotate said base around said center point in the field of view of the interrogating doppler radar for functioning to create a variable return signal from the interrogating doppler radar signal.
