Abstract
1. Способ передачи телеметрической и видеоинформации с частотно-временным уплотнением радиоканала и аналого-цифровым методом частотной (фазовой) модуляции несущей частоты N (где N=2, 4, 8…) синхронными видеопотоками, в каждом из которых на тактовой частоте Fосуществляется разделение каналов во времени со скважностью Q=2, при этом каждый поток разнесен от соседнего по несущей частоте на частотный интервал Δfp=F·n (где n=5, 6, 7…) и сдвинут по времени на половину такта, отличающийся тем, что, с целью расширения функциональных возможностей, высокочастотный сигнал видеоинформации повергают временной дискретизации, снижая разрешение и частоту кадров, генерируют маркерные видеоимпульсы, затем из полученных сигналов формируют один из синхронных потоков, который уплотняют с потоком телеметрической информации и передают по радиоканалу.2. Устройство для осуществления способа по п.1, содержащее последовательно соединенные генератор тактовых частот (1), делитель частоты (2), формирователь маркерного импульса (3), фазовый детектор (4), частотный модулятор (5), управляемый генератор (6) и усилитель мощности (7), опорный генератор несущих частот (8), выход которого подключен ко второму входу фазового детектора (4), к третьему входу которого подключен второй выход управляемого генератора (6), первый коммутатор (9), вход которого подключен ко второму выходу генератора тактовых частот (1), сумматор (10), включенный между выходом первого коммутатора (9) и вторым входом частотного модулятора (5), второй коммутатор (11), включенный между третьим выходом генератора тактовых частот (1) и вторым входом сумматора (10), формирователь частотной «подставки» (12), вкл�1. A method for transmitting telemetric and video information with time-frequency compression of a radio channel and the analog-to-digital method of frequency (phase) modulation of the carrier frequency N (where N = 2, 4, 8 ...) by synchronous video streams, in each of which channel separation is carried out at the clock frequency F in time with a duty cycle of Q = 2, with each stream spaced from the adjacent carrier frequency by the frequency interval Δfp = F · n (where n = 5, 6, 7 ...) and shifted in time by half a cycle, characterized in that, in order to expand functionality, high frequency ny plunged video signal sampling time, reducing the resolution and frame rate, generating video pulses marker, then the received signals from one form of synchronous flows, which condense with telemetric data stream and transmitted on radiokanalu.2. A device for implementing the method according to claim 1, comprising a series-connected clock generator (1), a frequency divider (2), a marker pulse shaper (3), a phase detector (4), a frequency modulator (5), a controlled generator (6), and a power amplifier (7), a reference carrier frequency generator (8), the output of which is connected to the second input of the phase detector (4), to the third input of which the second output of the controlled generator (6) is connected, the first switch (9), the input of which is connected to the second the output of the clock generator (1), total OP (10), connected between the output of the first switch (9) and the second input of the frequency modulator (5), the second switch (11), connected between the third output of the clock generator (1) and the second input of the adder (10), frequency “stand” driver »(12), incl�
