=== Introduction ===
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 ===
LOFAR may benefit from thinking of these transient signals as more than RFI.  Early investigations are described in a presentation at an August

Some work [[science:sudden ionospheric disturbances | ongoing]] on using reflected RFI to study transient phenomena, such as GRBs.
