Abstract
A wave guide scanner assembly having an oscillating support for a scanning antenna which is driven by an assembly having no contacting components. The scanner assembly is particularly useful for motor vehicular collision warning systems. The drive assembly for the oscillating support includes a coil and magnet for driving the support when current is applied thereby resulting in translational movement of the magnet and oscillating movement of the support. A spring flexure assembly is connected to the support for providing controlled harmonic oscillation to the support and antenna.
Claims15
A sensing system comprising:
- (a) an antenna scanner assembly including a moving support rotatably mounted to a chassis and also mounted to a scanning antenna;
- (b) a drive assembly for oscillating said moving support;
- and
- (c) a transceiver coupled to said scanning antenna for transmitting radar signals to a target as said scanning antenna is oscillated,
- wherein said drive assembly for said moving support has no components in contact with said moving support.
A wave guide scanner assembly including a moving support rotatably mounted to a stationary chassis, a scanning antenna connected to said moving support, and a drive having no components in contact with said moving support for providing oscillating movement of the moving support and antenna.
A wave guide scanner assembly including an oscillating support for an antenna and a drive assembly for the support, the drive assembly having no components in contact with the oscillating support.
