Yeah, as a kid with a shortwave radio I had no idea what it was. I used to tune numbers stations and wonder what they were all about, too. Back then, you couldn't just Google it.
I think the official explanation of the "woodpecker" fits, though - ionospheric over-the-horizon radar. Similar in concept to this one: http://www.defence.gov.au/dmo/esd/jp2025/jp2025.cfm
