Однако такое устройство требуетдля обеспечения компенсации полукруговой радиодевиации значительной мощности.However, such a device requires to provide compensation for semicircular radio deviation of significant power.

Цель изобретения - уменьшение мощности в замкнутом следящем контуре при электрической компенсации полукруговой радиодевиации.The purpose of the invention is the reduction of power in a closed servo loop during electrical compensation of semicircular radio deduction.

Указанная цель достигается за счет того, что в гониометре дополнительная компенсирующая катушка расположена ортогонально по отношению к пеленгующей искательной катушке гониометра и соединена с выводами одной из его полевых катушек через дроссели с одинаковыми величинами индуктивностей, выбираемыми в зависимости от величины компенсирующей радиодевиации.This goal is achieved due to the fact that in the goniometer, an additional compensating coil is located orthogonally with respect to the direction-finding search coil of the goniometer and is connected to the terminals of one of its field coils via chokes with the same inductance values, selected depending on the value of the compensating radio deviation.

На чертеже показана функциональная блок-схема автоматического радиокомпаса (АРК).The drawing shows a functional block diagram of an automatic radio compass (ARC).

Устройство содержит две взаимноперпендикулярные HanpaBneHHbief антенны 1 и 2, подключенные к гониометру 3, дроссели 4 и 5 и замкнутую следящую систему 6, подключенную к пеленгующей искательной катушке 7 гониометра 3, расположенной перпендикулярно к доз 824091 4 лоЛнительной компенсирующей катуш- по амплитуде и противофазное нежелаке 8 гониометра 3.The device contains two mutually perpendicular HanpaBneHHbief antennas 1 and 2 connected to the goniometer 3, throttles 4 and 5 and a closed tracking system 6 connected to the direction-finding search coil 7 of goniometer 3 located perpendicular to doses 824091 4 goniometer 3.

Компенсирующая катушка 8 через дроссели 4 и 5с одинаковыми величинами индуктивностей подключена к вы- ₅водам одной из полевых катушек 9 и 10 гониометра 3, соединенных с антеннами 1 и 2.The compensating coil 8 is connected through chokes 4 and 5 with identical inductances to the terminals _{5 of} one of the field coils 9 and 10 of goniometer 3 connected to antennas 1 and 2.

Компенсация полукруговой девиации осуществляется следующим образом.Compensation for semicircular deviation is as follows.

Эффект возникновения полукруговой девиации в АРК эквивалентен добавлению к ЭДС направленной антенны 1 или 2 некоторого нежелательного напряжения , синфазного принимаемому сигналу и ₍₅пропорционального по.амплитуде напряженности поля в точке приема. При пеф ленговании сигнала пеленгующая искательная катушка 7 гониометра 3 с помощью следящей системы 6 автоматически устанавливается’ в .положение минимума диаграммы направленности приема. В этом положении к выводам дополнительной компенсирующей катушки 8 приложе- . но напряжение, амплитуда которого со- _?5ответствует максимуму диаграммы направленности и пропорциональна напряженности поля в точке цриема, а фаза при соответствующем выборе полярности компенсирующей катушки 8 противоположна указанному выше нежелательному напряжению. Вывод’ы компенсирующей катушки 8 соединены с выводами одной из полевых катушек 9 или 10 в зависимости от компенсируемого коэффициента радиодевиации через схему параллельной 35 обратной связи, элементами которой могут служить, например, высокочастотные дроссели 4 и 5 с одинаковыми величинами индуктивностей, выбираемыми в зависимости от величины компенсируемой радиодевиации. Так как в полевую катушку вводится напряжение, равное тельному напряжению, то тем самым ком- . пенсируется полукруговая радиодевиация .The effect of the appearance of semicircular deviation in the ARC is equivalent to adding to the emf of the directional antenna 1 or 2 some undesirable voltage in phase with the received signal and ₍₅ proportional to the amplitude of the field strength at the receiving point. When peering the signal, direction-finding search coil 7 of goniometer 3 using a tracking system 6 the position of the minimum radiation pattern is automatically set to “.” In this position, voltage, amplitude is applied to the terminals of the additional compensating coil 8. otorrhea _{co-? 5} sponds maximum radiation pattern and is proportional to the field intensity at the point tsriema and phase at the appropriate choice of the polarity of the compensating coil 8 opposite to the above-mentioned undesirable voltage. Vyvod'y bucking coil 8 are connected to one terminals of the field coils 9 or 10 depending from the compensated radio deviation coefficient through a parallel feedback circuit 35, the elements of which can serve, for example, high-frequency chokes 4 and 5 with the same values of inductance features selected depending on the magnitude of the compensated radio deviation. Since a voltage equal to the actual voltage is introduced into the field coil, thereby semicircular radio deviation is being retired.

Предлагаемая схема компенсации полукруговой девиации позволяет снизить мощность двигателя следящей системы ,в 4 раза и на 50% повысить надежность АРК.The proposed compensation scheme for the semicircular deviation allows to reduce the engine power of the tracking system, to increase the reliability of the ARC by 4 times and by 50%.

Claims

The invention relates to radio engineering, in particular, to radio navigation systems for determining the heading angle of a radio station on moving objects (airplanes, ships, etc.). Automatic radio compasses tlt l are known and containing fixed antennas connected to the goniometer and the following system. The disadvantages of such devices are their limited functionality. The closest to the present invention is an automatic radio compass containing two fixed, mutually perpendicular directional antennas connected by their outputs with a goniometer, and a closed tracking system. 4. However, such a device requires significant power to compensate for the semicircular radio de-variation. The purpose of the invention is to reduce power in a closed servo loop when electrically compensating for semicircular radio deviation. This goal is achieved due to the fact that, in the goniometer, the additional compensating coil is distributed orthogonally with respect to the direction finder of the goniometer and connected to the terminals of one of its field coils via chokes with the same inductance value, depending on the compensating radio variation. The drawing shows a functional block diagram of an automatic radio compass (ARC). The device contains two mutually perpendicular HanpaBneHHbief antennas 1 and 2, connected to the goniometer 3, throttles 4 and 5, and a closed tracking system 6 connected to the direction finder 7 of the goniometer 3, perpendicular to the additional compensation coil 8, and the 8 giometer. through the chokes 4 and 5 with the same inductance values, they are connected to the terminals of one of the field coils 9 and 10 of the goniometer 3 connected to antennas 1 and 2. The semicircular deviation is compensated as follows. The effect of the semicircular deviation in the ARC is equivalent to adding a directional antenna 1 or 2 of some unwanted voltage to the PDS, in phase with the received signal and proportional to the amplitude of the voltage of the field at the point of reception. When direction finding the signal, the direction finder coil 7 of the goniometer 3 with the help of the tracking system 6 is automatically set to the minimum position of the reception pattern. In this position, the conclusions of the additional compensating coil 8 are attached to the gage, the amplitude of which corresponds to the maximum of the directivity pattern and is proportional to the field strength at point 1; 1 and the phase with the appropriate choice of the polarity of the compensating coil 8 is opposite to the indicated undesirable voltage. Conclusion of the compensating coil 8 is connected to the terminals of one of the field coils 9 or 10, depending on the compensated radio de-evolution coefficient through a parallel feedback circuit, elements of which can serve, for example, high-frequency chokes 4 and 5 with the same inductance values chosen depending on values of compensated radio variation. Since a voltage equal to 8–14 in amplitude and antiphase unwanted voltage is introduced into the field coil, the semicircle radio deviation is compensated by this very same one. The proposed semicircular deviation compensation scheme allows reducing the power of the tracking system's engine by 4 times and increasing the reliability of the ARC by 50%. The invention is an automatic radio compass containing two fixed, mutually perpendicular directional antennas connected by their outputs with a goniometer having an additional compensating coil and a closed tracking loop, characterized in that, in order to reduce power in a closed tracking loop when electrically compensating for a semicircular radio deviation The additional compensating coil is located orthogonal with respect to the direction finder of the goniometer and is connected to the terminals Noah from its field coils through chokes with the same inductance values.
