We see these "beam streaks" regularly in the southwest and there
is little doubt that it is interference from military
operations. Military aircraft will routinely emit ECM
(electronic countermeasures) as part of their training missions.
Many times we see these originating from southern Nevada (home
of Nellis AFB Test Range -- and to some, Area 51 ;-). This
probably means they are testing one of their still secret aircraft.
Occasionally it appears when two radars are pointing directly at
each other. The received power greatly exceeds the normal value.
Finally, note the long, narrow streaks in southern California in
his example image. Those are the signatures from chaff dropped
by military aircraft as part of their ECM.
It also appears at sunrise/sunset as mentioned in an earlier reply.
