Description

Известные способы селекини подвижных радиолокационных целей, используемые в импульсно-допплеровских радиолокационных системах, основанные на записи отраженных от цели сигналов и сравнении записанных сигналов с последующими отраженными сигналами, поступившими на вход приемного устройства, не обеспечивают полной взаимной компенсации двух сравниваемых противофазных сигналов даже при полной их идентичности, так как один из этих сигналов неизбежно будет искажен трактом записи.Known methods of selekine mobile radar targets used in pulse-Doppler radar systems based on recording signals reflected from a target and comparing recorded signals with subsequent reflected signals received at the input of a receiving device do not provide full mutual compensation of two compared antiphase signals even when they are completely identity, since one of these signals will inevitably be distorted by the recording path.

В предложенном способе повышение точности компенсации идентичных сигналов достигнуто последовательной записью на трубке с накоплением зар дов двух соседних противофазных сигналов и воспроизведением записи результирующего разностного сигнала. Вследствие того , что по тракту записи проход т оба сигнала, искажени  их в процессе записи при воспроизведении будут взаимно компенсироватьс .In the proposed method, an increase in the accuracy of compensation of identical signals is achieved by sequential recording on the tube with the accumulation of charges of two adjacent antiphase signals and reproduction of the recording of the resulting difference signal. Due to the fact that both signals pass through the recording path, their distortions in the recording process will be mutually compensated during playback.

В соответствии с описываемым способом процесс селекции целей осуществл етс  путем непрерывного чередовани  трех циклов работы, трубки с накоплением зар дов. Во врем  первого цикла на модулирующий электрод трубки подают отраженный от цели сигнал с положительной пол рностью, который записываетс  в виде потенциального рельефа на мишени трубки. Во врем  второго цикла на модулирующий электрод подают последующий отраженный сигнал с отрицательной пол рностью, который записываетс  на том же участке мишени, где уже записан сигнал с положительной пол рностью. Во врем  третьего цикла на модулирующий электрод трубки подают посто нное напр жение и производ т воспроизведение записанных во врем  первых двух циклов сигналов. Полученный после считывани  разностный сигнал 150140In accordance with the described method, the process of target selection is carried out by continuously alternating three cycles of operation, a tube with an accumulation of charges. During the first cycle, a signal with a positive polarity, reflected from the target, is fed to the modulating electrode of the tube, which is recorded as a potential relief on the tube target. During the second cycle, the next reflected signal with a negative polarity is fed to the modulating electrode, which is recorded on the same portion of the target where the signal with a positive polarity is already recorded. During the third cycle, constant voltage is applied to the modulating electrode and the signals recorded during the first two cycles are reproduced. Received after reading the difference signal 150140

Наличие разностного сигнала свидетельствует о по влении в зоне обзора станции движущейс  цели.The presence of a difference signal indicates the occurrence of a moving target in the station's field of view.

Предмет изобретени Subject invention

Способ селекции подвижных радиолокационных целей с записью отраженных сигналов, отличающийс  тем, что, с целью сравнени  сигналов с последующими отраженными сигналами, применены три непрерывно чередующихс  цикла работы: цикл записи сигналов в положительной пол рности, цикл записи сигналов в отрицательной пол ркости и цикл воспроизведени  записей, полученных в двух предществующих циклах.A method for selecting mobile radar targets with recording reflected signals, characterized in that, in order to compare signals with subsequent reflected signals, three continuously alternating cycles of operation are used: the cycle of recording signals in positive polarity, the cycle of recording signals in negative polarity, and the cycle of reproducing signals received in two previous cycles.
