| echoes | <radiobiology> Wave packets (pulses) which have been reflected or otherwise returned to the detector, which are sufficiently delayed and retain sufficient magnitude so that they are perceived as a signal distinct from the one transmitted directly. (In other words, just like sound echoes, only for analogous phenomena with other waves.) (09 Oct 1997) |
