Samenvatting
The requirements for a distance sensor to realise adaptive cruise control (ACC) were studied, and 76GHz radar for the ACC was developed. This is Frequency Shift Keying (FSK) radar, which transmits two frequencies in time-duplex, and a monopulse feature detects the azimuth angle of targets without a scanning mechanism. A fully MMIC (Monolithic Microwave Integrated Circuits) 76GHz module and signal processing electronics are combined into a single compact unit. Basic radar performance gave good results. The mechanism of multi-pass interference was studied, and a new feature of the algorithm to discriminate multiple stationary targets functioned satisfactorily.
