Narrative:
We were on the VOR-a approach at smo and had descended to 1110 ft MSL -- the MDA for that section of the approach. The tower said they had a low altitude alert on us. We advised them of our altitude, and they said our descent rate may have set off their low altitude alarm on the radar even though we weren't below the published descent altitude.
