Bid ch.rme 1 ^ _{e to the radiator} ,

Location of the _{ship radar} equipment must be according to the

according to the regulations the own pre-alignment of the

Ship appear as a luminous line on the screen 11. In Fig. 1 this is indicated by the bearing line P ₀ .

To write a bearing line P, for example the bearing line Po for the pre-alignment, a bearing line pulse ρ is applied to the cathode 6 of the picture tube 7, which begins at the moment the transmission pulse a is emitted by the radiator 1 and after a predetermined display period corresponding to the selected display period , Representation time At is to end at the edge of the screen 11, which will be discussed in greater detail below.

In addition to the corresponding one of the pre-alignment bearing line P _0, any other bearing lines can Pauf the screen are drawn by, for example during the return beam locating detected target points Z \ and _Z2 continuous bearing lines P \ and _P2 in Fig. 1. ρ To generate the Peillinienimulse to a Bearing line pulse generator 13 is provided. This bearing line pulse generator 13 is controlled by gate pulses d , which are supplied by a gate pulse generator 15, which in turn is triggered by trigger pulses s from the transceiver 3 at the beginning of each display period. The length of the bearing line pulses ρ corresponds to a distance measuring range to be displayed on the screen U in accordance with the display time Δ t. Bearing line pulses p at the output of the bearing line pulse generator 13 should only occur if a direction pulse r has also been sent from a direction pulse generator 14 to the bearing line pulse generator 13. This direction pulse generator 14 can be formed by any suitable electromechanical, electronic, magnetic or other contactor that responds at the moment when the current direction of the rotating radiator 1 with a predetermined direction, for example the direction of your own ship or the bearing of a located and object of interest.

It now becomes the function of the bearing line pulse generator 13 described with the aid of an embodiment for the device according to the invention, in which two bistable multivibrators 16 and 17, each with a ~> static preparation input 16.1,17.1 and one each dynamic trigger input 16.2 and 17.2 provided are. For the embodiment according to FIG. 1 selected bistable flip-flops 16 and 17 have the Function of the so-called "D-type", d. H. if a preparation input 16.1 or 17.1 is positive Potential, the next signal with a positive edge at the triggering inputs 16.2 resp. 17.2 that the output 16.3 or 17.3 assumes positive potential. A preparation input 16.1 or 17.1 with On the other hand, zero potential has the effect that the assigned output 16.3 or 17.3 at the next signal with a positive edge at the trigger input 16.2 or 17.2 also assumes zero potential. The outputs 16.4 and 17.4 each lead the inverse signal to the outputs 163 and 17.3.

In the switching device according to FIG. 1, the preparation input 16.1 is connected to the output of the direction pulse generator 14 and the preparation input 17.1 of the second flip-flop 17 is connected to the second output 16.4 of the first flip-flop 16. The triggering inputs 16.2 and 17.2 of the flip-flops 16, 17 are connected to the gate pulse generator 15 so that a Torimouls d are effective at the triggering input 16.2 of the first triggering stage 16 and the inverted gate pulse d is effective at the triggering input 17.2 of the second triggering stage 17. The outputs 16.3 and 17.3 of the two trigger stages 16 and 17 are connected to inputs 18.1 and 18.2 of an AND stage 18.

The gate pulse d controlling the display time At is normally also supplied as an inverted gate pulse d from the gate pulse generator 15, otherwise, as in FIG. 1, an ordinary inverter stage 15a is to be interposed. Is the direction im-

ίο pulse r the preparation input 16.1 of the first bistable flip-flop 16 positive, then the positive edge of the gate pulse d which then appears sets the output 16.3 positive; thus a bearing line start pulse / occurs at an input 18.1 of the AND stage 18.

The second bistable multivibrator 17 has positive potential at its output 17.3 in the idle state, see above that the AND stage 18 switches through and emits a bearing line pulse ρ at its output 18.5. the second output 16.4 of the first bistable flip-flop! 6, which is connected to the preparation input 17.1 of the second bistable flip-flop 17 is connected, by now assuming the potential zero, delivers to the preparatory

. input 17.1 of the second bistable flip-flop 17, the preparation potential g, so that the next

ij positive edge of the inverted gate pulse d at input 17.2 of the second bistable multivibrator 17 whose output 17.3 switches to zero potential. So this happens, as also from the illustration in FIG. 2 can be seen, exactly at the end of a gate impulse d. This ends the bearing line pulse ρ again, and its duration thus corresponds exactly to the duration of the gate pulse d and thus the current display time Δ t.

After the end of the directional pulse r, which must be completed before the next bearing line P is to be written, the next following gate pulse d switches the first bistable flip-flop 16 back to its idle state, that is, zero potential is set again at its first output 16.3, whereby also the bearing line start pulse / "and thus the bearing line pulse ρ are ended again.

If, after the end edge of the direction pulse r, there is again zero potential at the preparation input 16.1 of the first bistable multivibrator 16, then as soon as the next positive edge of the inverted gate pulse d appears at the trigger input 16.2, the first output 16.3 changes from positive to zero potential back at the second output 16 , 4 appears positive potential, and the following positive flank of the inverted gate pulse d generates the rest state again at the output 17.3 of the second bistable multivibrator 17.3 - positive; Potential -; but no new pulse is emitted at the output 18.5 of the AND stage If, because the first input 18.1 has already received zero potential again with the previous termination of the bearing line start pulse /.

In order to be able to switch off the display of bearing lines P, if desired, the AND stage Ii a third input 18.3 can be provided which is connected to a switch 19 in order to selectively zero it or to lay positive potential. With an additional fourth input 18.4, ei Identification modulator 20 be connected, for example: by a periodic interruption in to it known way to bring about an identification of bearing lines.

As a modification within the scope of the invention, for. I also the direction pulse generator 14 for optional Creation of one or more bearing lines P fixed or

be executed freely selectable direction assignment, as for example in the patent application cited at the beginning is described.

This function of the bearing line pulse generator 13, which is here on the special embodiment of a

Memory circuit from bistable multivibrator ver logic has been described, η Realize the design and functional logic with the usual storage detailed switchgear.
