1. In a radar display system of the type having means for transmitting and receiving radar signals via an antenna:
- cathode-ray tube means responsive to received radar signals for displaying information representative of an input applied thereto;
means responsive to the received radar signals for applying an input representative thereof to said tube means;
video storage and playback means for storing recorded video signals to be displayed by said tube means, said recorded video signals representing information different than the information represented by the received radar signals;
said circuit means being further responsive to said recorded video signals for applying an input representative thereof to said tube means;
means for selectively and alternatively connecting said received radar signal or said recorded video signal to said circuit means; and
means connected to the radar antenna and to said tube means for generating raster signals in synchronism with operation of the antenna, to effect display of information represented by said selected input;
whereby said cathode-ray tube means displays information representative of either said received radar signals or said recorded signals in response to said raster signals and said selected input.
