Abstract
A radar system with frequency scanning beam steering is described for in-vehicle occupant detection and classification for seat-belt reminder functionality (SBR) and airbag suppression. The system includes an antenna system for which the main lobe direction (azimuth angle ö) is changing mostly linearly over frequency, a RF electronic transceiver electronic with at least one transmit channel and one or multiple receive channels with two outputs (I/Q) per channel. The data acquisition and signal processing/interpretation are made by a microcontroller system.
