Microwave Crash Sensor for AutomobilesHolmstrom, F. R.; Hopkins, J. B.; Newfell, T.; White, E.; U.S. Department of Transportation; Lowell Technological Institute (International Foundation for Telemetering, 1971-09)A prototype microwave radar anticipatory crash sensor for automotive applications is described. This system is for prospective use in conjunction with passive occupant restraints--protective devices that require no action on the part of the occupant to insure their effectiveness. Appropriate antenna configuration and circuitry permit position, velocity, and size discrimination of the target in a simple manner. Results of field tests are discussed, including the manner in which system parameters and target characteristics relate to the tradeoff between false alarm rate, miss rate, and system complexity.
