The signal you are describing is probably a CODAR or WERA radar, but without a bit more information, or maybe a recording, it is impossible to say for sure what you are hearing.  Specifically, it might be the long range CODAR in Diablo Canyon, California, that has the designation DCLR.  But, since I don't know your location it could be one in Europe also, there are CODAR / WERA there around that freq, especially in the Mediterranean area.

So I can't say what that noise is, but I can provide more information on it.
If you go to http://websdr.ewi.utwente.nl:8901/ and then tune into 4450 kHz AM you can hear it.
Sorry if this doesn't do much, this just caught my attention so I thought I'd pitch what I knew.

EDIT: So I forgot to say, but this receiver is located in the Netherlands
