Description

(54) DEVICE FOR IMITATING SIGNALS OF POINT OBJECTS

the third is with the fifth output of the control unit. The first and second outputs of the maneuver simulator are connected to the third and fourth keys 2, respectively.

The drawback of the device is the inadequate accuracy of the device, due to the inability to simulate the approach or expansion of two point objects, the law of motion of which is determined by the instructor, which reduces the level of professional training of the operator, increases the difficulty of evaluating his work.

The purpose of the invention is to improve the accuracy of the device.

The goal is achieved in that the device containing the keys, the inputs of one of which are connected to a pseudo-random pulse sequence generator, with the control unit and the clock pulse generator, the others are connected to the control unit and the generator of pseudo-random pulse sequences, and the outputs of the keys are connected to corresponding inputs of the first and second reversible counters, and sequentially connected master oscillator, a counter connected to a clock generator pulses, and a comparator unit connected to the second reversible counter, serially connected strobe pulse generator, connected to the control units, and pulse pulse generator connected to the master pulse generator, the third reversible counter connected to the control unit, the adder connected to the first reversible counter counter, and a switch connected to the first reversible counter and to the comparison unit.

The drawing shows the block diagram of the device. roystva

The device includes a master oscillator 1 pulses, a counter 2, a shaper of 3 clock pulses, a block 4 of comparison, a generator of 5 pseudo-random sequences of pulses, the first 6, second 7, third 8 and fourth 9 keys, first Yu and second 11 reversible counters, shaper pulse shaper 12 , shaper GZ bursts of pulses, the third reversible counter 14, the adder 15, the switch 16, block 17 control.

The operation of the device is as follows.

The output signal of the master oscillator 1 is fed to the input of the counter 2, the output pulses of which are normalized by the duration and amplitude in the clock generator 3. The generated frame clock sequence of the frame frequency from the output of the clock generator 3 serves to clock the pseudo-random sequence generator

pulses 5. In the pulse generator 5, four different sequences of pulses are received, two of which are fed through keys 6 and 7 to the counting inputs of the reversible counters 10 and 11, and the other two -

to the control inputs “addition-subtraction of the same counters via keys 8 and 9. Pulse sequences that feed the control inputs“ addition-subtraction of reversible counters 10 and I will change the operation mode of reversible counters 10 and 11 according to a random law. This means that with the arrival on the control input of the reversible counter 10 or I of the pulse, it operates in the subtraction mode, and in the absence of the pulse, in the addition mode. In turn, the counting pulses, which are fed to the reversible counters 10 and 11, are also pseudo-random sequences of pulses. As a result of the filing of such sequences of pulses at the bits of the reverse

0 counters 10 and 11 receive pseudo-random sequences of parallel codes. Neighboring codes can differ from each other only by one binary unit. Parallel codes from reversing bits

5, the counter 11 is fed directly to the unit 4 of the comparison, and from the bits of the reversible counter 10 — through the switch 16. The codes from the reversible counter 10 are also fed to the input of the adder 15, where they are added to the codes of the reversible counter of points 14. The resulting code from the output adder 15 is supplied via switch 16 to the input of comparator unit 4. In the comparison block 4, these codes are compared with the counter code 2. At the output of the comparison block 4, as a result of the comparison codes, a signal is received that is a sequence of equal amplitude and duration of the rectangular video pulses. Since the generator of pseudo-random sequences of pulses 5 is clocked with the image frame rate, the code change of the reversible counters 10 and 11 will occur once per frame and not more than by one binary unit. Video pulses from the output of the comparison unit 4 are fed to the input of the imaging unit 12, where a pulse is generated with a duration defined by a signal that is supplied from the output of the control unit 17 to the input 12 of the imaging unit. The generated pulse from the output 12 of the imager serves on one input of the imager packs 13 pulses, to the other input of which serves from the output of the master oscillator 1 a sequence of high-frequency pulses. In the former 13, the pulse sequence of the master oscillator 1 is gated. From the output of the former, the packet of 13 pulses is received, the received pulse train is fed to the counting input of the reversible counter 14, in which the incoming pulses are counted.
