Description

.,.one

The invention is fireproof and can be used in automatic control and monitoring systems used, for example, in radar.

Known correlator, working on a relay algorithm, the contents of the amplifiers-limiters in each of the two channel 06, the outputs of which are by the key to the ambiguity elements, the delay unit, the linear-frequency converter: reversible counters - drives and the delay unit l. This correlator requires the use of an analog-pulsed 6-step multiplication (block forming a linear frequency converter module, a key, a counter). A digital correlator containing an adder, the first and second analog-to-digital converters, whose inputs are the first and second inputs of the correlator, the sign outputs of the analog-digital converters are connected to the first and second inputs of the unequal element, respectively. In addition, the correlator contains a pseudo-random number generator, a switchboard and other matching units 2J. However, it is characterized by a low accuracy determined by the operation algorithm and its structure.

The aim of the invention is to improve the accuracy. In the described corrello torus, this is achieved by the fact that in it the bit outputs of the first and second analogue

digital converters are connected respectively to the first and second inputs of the adder, the control input of which is connected to the output of the inequality element.,;., -., .-.

The drawing shows the structural scheme of the described / correlator.

It contains analog-to-digital converters (ADC) 1 and 2, Element of inadequate 3, adder 4, input 5 ADC 1, input 6 ADC 2, output 7 of the binary sign bit of the first signal, output 8 numeric bits of the magnitude of the input signal module, binary output 9
