MICROWAVE CRASH SENSOR FOR AUTOMOBILES

The patent concerns a vehicle safety system in which a bistatic Doppler system senses objects in the path of the vehicle and activates a passenger restraint device, such as an inflatable 'air-bag' in response thereto. In another preferred embodiment, the Doppler system is combined with mechanical sensing apparatus to deploy the restraint device during lower speed collisions. In addition, a system is disclosed that deploys a passenger restraint device only in response to simultaneous signals from two Doppler systems.
