Description

one

The invention relates to electronic digital devices, in particular, can be used to control the beam scanning of a phased antenna array and to control the beam scanning in the radar station indicators.

An address shaper is known that contains a source data storage device, a control device and a counter with counting and register inputs.

In a known driver, when the control device is started from an external pulse, the counter is first set to zero, then its register input is connected to the source data memory device stored in the register, memory, etc. Then the register input of the counter is turned off, and its counting input is connected to a clock pulse generator, the pulses of which change the address taken from the counter. If the counter overflows, it is reset, i.e. the circuit returns to its original state.

In some cases, for example, when working on aircraft radars, it is necessary to take into account the displacement of the aircraft relative to the viewed space and at the same time fill the viewed area of a given scanning sector, which cannot be done in a known driver.

The purpose of the invention is to provide the possibility of adjusting the address of the scanning device. The goal is achieved by the fact that in the proposed

the scanner address driver, the register input of the address counter is connected to an initial conditions adder, which is connected to the address correction sensor via a converter and a memory device of the scanned scan sector, the count input of which is connected to the count input of the address counter, and the register input is connected to the memory device source data and is associated with a trigger that serves

to set the extreme position of the scanning sector, which is connected to the general reset circuit of the control unit and connected to the reset circuit of the scanning sector memory device and to the counting input of the address counter, the converter, the scanning sector memory device and the address counter being connected to the control unit via keys that are connected to an input frequency shaping device

address correction.

The drawing shows the block diagram of the proposed shaper address of the scanning device. Here, the register input of the address counter 1 is connected to the adder 2, the head of the controller, which is connected to the address correction sensor 3 via the converter 4 and to the device 5 of the scanning sector memory. The latter is connected to the device 6 memory t1I; source data associated with the switch, the tele of 7 modes and with the trigger 5, ensuring the installation of the circuit to the extreme position of the scanning sector entering the control unit. The device reset circuit is connected via a key 9 to the decoder of the control device 10 connected with the device 11 for generating the address correction input frequency.

The control unit consists of the switch 7. Modes, trigger 8, key I counter 12, decoder 13, triggers 14, 15, keys 16, .17, 18, 19, generator 20, generator 21 general reset and circuit OR 22.

The proposed shaper address scanning device operates as follows.

After the operation mode is set by switch 7, a pulse is generated at the output of the general reset shaper, which triggers trigger 15, which causes the counter 12 to be reset and a signal appears on the zero bus of the decoder 13, which triggers trigger 14. 14. The trigger 14 connects the counter input 12 to generator 20 (connects the frequency /, i) and disconnects the key 19 and the second generator output 20 (frequency / а) from the input of the address counter /, from the input of the correction frequency input device 11 and from the memory device 5 scanning torus. Upon receipt of the pulses at the input of the counter 12 at the output of the decoder 13 alternately pulses appear on the tires from the first to the seventh. The signal taken from the first bus ensures that the previous information in the converter 4 is erased and connected to the address correction sensor 3. The signal taken from the second bus triggers the trigger 8, which disables the register input of the device 5 of the memory area of the scanning sector from the reset circuit. The signal taken from the third bus transfers the trigger 8 to the opposite state (in the presence of a signal from the general reset generator), which ensures that the reset circuit is connected to the register input of the device 5 of the scanning sector area memory. The signal taken from the fourth bus ensures the reset of the device 5 of the memory of the scan sector zone (with

the presence of a signal from the generator general reset). The signal removed from the bus bus resets the counter 1, the device for shaping the input correction frequency and

trigger 15. The signal taken from the sixth bus connects the register input of the address counter / to the output of the adder 2 of the initial conditions. The signal taken from the seventh bus triggers the trigger 14, locking the key 16 and opening the keys 17 and 19. At the same time, the counting inputs of the address counter / and the device 11 for shaping the correction input frequency receive pulses of frequency fz from the generator

20. When the number of pulses corresponds to the specified correction input frequency, a pulse is generated at the output of the correction input frequency shaping device, which ensures reset of the counter 12. At the same time, the control device works similarly, only the signal from the third bus of the decoder 13 does not trigger, because the signal with the former 21, there is no general reset.

When the device 5 is filled up (or when the setpoint is set), the scanner sector 5 memory will produce a signal at the output that ensures the start of the general reset, which initializes the device.

The address driver can have an integrated design, for example, on MicroWatt-1 chips.
