Title: Switching arrangement for DA conversion of radar data - has comparator connected to main store and to output device corresponding to cathode ray deflection
Inventor: MUELLER MANFRED
IPC: G01S7/295
Filed: 1974-11-09
Abstract: A buffer store stores the incoming radar data and three preliminary stores receive the maximum amount of radar data from an azimuth sector whose position is not given, but whose angular range is given. A control device causes, in cyclic sequence, the recording in one of the three preliminary stores of the radar data in the buffer store, so that the three preliminary stores always contain the radar data originating from three connected azimuth sectors of angular value equal to the given azimuth sector. A main store receives the radar data in cyclic sequence from the three preliminary stores.

Title: Superheterodyne local oscillator - can be switched over from operation as variable frequency oscillator to locked operation
Inventor: DAUTH FRITZ-JOERG
IPC: H03L7/20
Filed: 1975-10-21
Abstract: When the variable frequency operation is switched on the oscillations are repeatedly counted during an accurately fixed time interval determined by a reference oscillator. A reversible counter is used. The counting result is displayed. When the locked operation is switched on, the same counter counts the oscillations backwards, starting from a reading taking into consideration the receiver or transmitter I. F. The counting is carried down to the I. F. and on reaching it the counter delivers a pulse whose phase relation is compared with the reference oscillator pulses in a phase discriminator (18). The phase discriminator delivers a control voltage for a reactance circuit, e. g. a capacitance diode of the local oscillator.
