Description

Известный способ определени  оптимальной рабочей частоты, основанный на наклонно-возвратном зондировании ионосферы, требует применени  нескольких .частот и специального оборудовани .The known method of determining the optimal operating frequency, based on the oblique-return sounding of the ionosphere, requires the use of several frequencies and special equipment.

Предлагаемый способ позвол ет упростить процесс измерений- Это достигаетс  использованием дл  определени  оптимальной рабочей частоты действующего оборудовани  радиоцентра с применением только одной частоты.The proposed method allows to simplify the measurement process. This is achieved by using to determine the optimum operating frequency of the operating equipment of the radio center using only one frequency.

Сущность описываемого способа состоит в следующем. При помощи передатчика, предназначенного дл  радиосв зи, излучают на одной из рабочих частот высокочастотные импульсы в направлении на корреспондента. Принима  отраженные сигналы, определ ют врем , прошедщее между посылкой рабочих и приемом отраженных сигнало1В , по времени определ ют ближнее рассто ние, на котором имеет место наибольща  интенсивность отраженного сигнала дл  рабочей частоты действующего передатчика. Очевидно, что это ближнее рассто ние соответствует одному «скачку волны или одному отражению волны от ионосферы и примерно равно зоне молчани . Дл  этого рассто ни  волна, на которой производилось наклонно-возвратное зондирование, будет оптимальнойОпределение оптимальной волны дл  других рассто ний в пределах одного «скачка производитс  расчетным путем с использованием соответствующих пересчетных коэффициентов- Пересчетные коэффициенгы представл ют собой отнощение косинусов углов падени  волны на ионосферу в зависимости от рассто ни  с некоторым поправочным коэффициентом , полученным опытным путемПредмет изобретени The essence of the described method is as follows. By means of a transmitter intended for radio communication, high-frequency pulses are directed at one of the working frequencies in the direction of the correspondent. Receiving the reflected signals, determining the time elapsed between sending the workers and receiving the reflected signals 1B, determine the short-distance distance over which the greatest intensity of the reflected signal takes place for the operating frequency of the current transmitter. Obviously, this short distance corresponds to one "wave jump or one wave reflection from the ionosphere and is approximately equal to the zone of silence. For this distance, the wave at which the oblique-return sounding was performed will be optimal. The determination of the optimal wave for other distances within one "jump is produced by calculation using appropriate conversion factors. from a distance with some correction coefficient obtained by experiment
