Title: Device for producing marker traces in position-finding installations
IPC: G01S7/22
Filed: 1970-12-11
Abstract: 1300470 Plan position indicators FRIED KRUPP GmbH 11 Dec 1970 [12 Dec 1969] 58986/70 Heading H4D A PPI system has a display timebase and a transmitter rotating synchronously and an A.C. signal representing the rotation is integrated and then compared with a selectable reference voltage wherein equality thereof causes a marker signal to be produced. The radar or sonar transmitter rotation is linked to the rotating deflector system of the display tube 4 and supplies signals Uo representing a reference direction (e.g. the vehicle heading or north) and U w  an A.C. timing signal (e.g. 50 cps sine wave). These are fed to unit 8 in which the A.C. signal is shaped into pulses and fed to a counter which is reset to zero by Uo. The counter output feeds a D-A converter whose saw-tooth output is compared with the output of a variable voltage generator 9. The comparator 7 output is fed via a pulse shaper 10 to the tube 4 to produce a marker and also to storage unit 12. If the set switch 16 is actuated when a marker signal is produced gate 17 passes the pulse shift register 18 which under the control of timing pulses U s  feeds the pulse after a delay equal to one rotation of the transmitter to the pulse shaper 10 to reproduce the marker. The pulse is also reinserted into the register. Individual markers may be deleted by actuating switch 22 or the whole register cleared by switch 23. In an alternative embodiment (Fig. 1, not shown) a plurality of generators 9 and comparators 7 are connected in parallel to the pulse shaper 10 each one producing a marker. The integrating stage 8 may alternatively be analogue.
