A system (10) is provided for detecting blockage of an automotive side object detection system ("SODS"). The system (10) includes a blockage detection processor (13), which is operative to determine whether an RF leakage signal level sensed between transmit and receive antennas (16, 18) of the system substantially match one or more of a plurality of pattern recognition information curves. If it is determined that the leakage signal level substantially matches one or more of a plurality of pattern recognition information curves, a blocked condition of the SODS is declared, as may be caused by mud, salt, ice, etc. The blockage detection processor (13) is further operative to determine whether the leakage signal exceeds a predetermined blockage threshold level. If the leakage exceeds the predetermined blockage threshold level, a blocked condition of the SODS is also declared. |
