Airbag releasing sensing system for motor vehicle

摘要: The sensing system (1) consists of six similar sensors (2), an evaluating unit (5) and a bent source (10), each sensor is constructed from transmitting/receiving stage (3), reception scanner (12), low-pass amplifier (14), driving (11). produces HF signal with frequency 76 GHz, radiated the antenna (4), characteristics as shown, mixes input directly into basis band,in self-oscillating mixing stage. In order to limit range measuring field diode switched on off by beat pulse.
