Ionized trails from meteors can reflect radio signals at frequencies in the LOFAR bands. This appears in CS1 data as short (100 ms) bursts of signal from a distant transmitter.
One application of this effect is in communications. For example, “Radio Burst Communications” is a way of transmitting information to/from areas that are not served by satellites.
LOFAR may benefit from thinking of these transient signals as more than RFI. Early investigations are described in a presentation at an August CS1 meeting.
Some work ongoing on using reflected RFI to study transient phenomena, such as GRBs.
