ИзвеоФжее способм жзмеренж малых рассто ний между объектши не позвол ют измер ть эти рассто ни на любом жа объектов«Because of the small distances between objects, these distances cannot be measured on any objects
Отличие предлагаемого способ заключаетс в использовании автогенератора с запаздывающей обратной св зью в виде канала распространений излучаемого сигнала от одного объекта к другому и обратно, отклонение частоты которого вл етс показателем изменени рассто ни объектамиThe difference of the proposed method lies in the use of an auto-generator with delayed feedback in the form of a channel of propagation of a radiated signal from one object to another and vice versa, the frequency deviation of which is an indicator of the change in the distance of objects
Насто щий способ позво-л ет производить одновременное измерени-е рассто ни на обоих объектах вThe present method allows simultaneous measurement of the distance on both objects in
На блок-схеме устройства объекты, между которыми измер етс рассто ние i , обозначены I и J,In the block diagram of the device, the objects between which the distance i is measured are denoted by I and J,

Модул1фованные колебани р ,, частотой близкой к р передаютс на приемник 5 объекта П-, S преобразователе б преобразуютс в другую несущую частоту и с помощью передатчика 7 передаютс на приемник 8 объекта I, далее на усилитель 2 и к измерителю 9 частоты Выход приемника 8 присоединен к усилителю 2, Таким образом замыкаетс кольцо обратной св зи через измер емое рассто ние «The modulated tunable oscillations p ,, with a frequency close to p are transmitted to the receiver 5 of the object P-, S converter b are converted to another carrier frequency and transmitted to the receiver 8 of the object I using transmitter 7, then to the amplifier 2 and to the frequency meter 9 Receiver output 8 is connected to amplifier 2. Thus, the feedback ring is closed through the measured distance "
Д устранени вли ни изменени амплитуда сигнала при изменении рассто ни приемник 8 должен иметь достаточно эффективное АРУ,To eliminate the influence of a change in the amplitude of the signal when the distance is changed, the receiver 8 must have a sufficiently effective AGC,
Нримен достаточно хорошо разв занные между собой приемную и передающую антенны, можно ретрансл ционную аппаратуру объекта П заменить пассивным отражателем.If the receiving and transmitting antennas are fairly well developed between each other, it is possible to replace the retransmission equipment of object P with a passive reflector.
