Abstract: A safety sensor and warning system, for use in combination with a motor vehicle, has sensors for determining if personnel are present in one or more predetermined danger zones proximate to the vehicle, during times when the vehicle is undergoing the loading and/or unloading of personnel; if the presence of such personnel is determined within any one or more of such danger zones related warning apparatus creates a sensory warning signal whereby the driver of the vehicle is made aware of such presence by the personnel; Microwave Doppler Shift Radar detects objects by reacting to a reflected radio signal of controlled strength and frequency which shifts off its original frequency when reflected off of an object of adequate density moving into, or changing position, within the range of the radiated radio signal and its consequent reflection; the sensors for determining if personnel are present in one or more predetermined danger zones utilize this known Microwave Doppler Shift Radar Technology and are electronica
