ABSTRACT:
A control circuit enables range and bearing markers on a p.p.i. radar display to be moved quickly and accurately. The control circuit has an input terminal receiving control pulses whose frequency of occurrence is manually selected, an output terminal for providing marker position-changing pulses and a series connection of a monostable device and a binary device, together with gating devices, so that the received control pulses are passed to the output terminal when the frequency of occurrence is below a certain value and so that a burst of position-changing pulses are provided, for each received control pulse, when the frequency of occurrence is above said certain value.
