Military TRACON controller allowed a PA46 to enter bur airspace without a handoff and bur controller was not aware of situation due to poor radar coverage to the west of vny. Poor coverage has been prevalent in this area since the ASR9 was installed in the bur area.

Narrative:
Point mugu ran an IFR aircraft into sct (bur area) airspace without a handoff. The aircraft was not observed by us due to bad radar coverage and IFF problems. Bur area has had these problems for several yrs and have got worse since the installation of ASR9. Point mugu was wrong for letting the aircraft enter our space, but the fact that we could not see the aircraft is dangerous and happens all too often. This problem has been idented in the past, but nothing seems to be done to fix this very serious problem.
