Description
II
Изобретение относитс к радиотехнике и может использоватьс в радиолокации , радиовысотометрии, в технике св зи, измерительных приборах дл полумени одиночных и периодически повтор ющихс сигналов с частот HOVI модул цией.The invention relates to radio engineering and can be used in radiolocation, radio altimetry, in communication technology, and in measuring instruments for half of single and periodically repeating signals with HOVI modulated frequencies.
Известен формирователь частотномодулированных сигналов, содержащий последовательно соединенные преобразователь колебаний с переменной частотой в последовательность импульсов с посто нной частотой следовани , первый импульсно-фазовый детектор , блок коррекции, сумматор, второй и третий входы которого соединены соответственно с выходом блока управлени частотой и выходом фильтра нижних частот, и управл емый генератор , второй импульсно-фазовый детектор,эталонный гемератор,а также синхронизатор,первый,второй и третий выходы которого соединены соответственно с входом установки нул преобразовател колебаний с переменной частотой а последовательность импульсов с посто нной частотой следовани , входом опорного сигнала первого импульсно-фазового детектора и управл ющим входом блока управлени частотой 1.A shaper of frequency-modulated signals comprising a series-connected oscillator with a variable frequency into a pulse train with a constant tracking frequency, a first pulse-phase detector, a correction unit, an adder, the second and third inputs of which are connected to the output of the frequency control unit and the low-pass filter output are known , and controlled generator, second pulse-phase detector, reference timer, as well as synchronizer, the first, second and third outputs of which They are connected respectively with the installation of a zero-frequency converter with variable frequency and a sequence of pulses with a constant tracking frequency, the input of the reference signal of the first pulse-phase detector and the control input of the frequency control unit 1.
Однако известное устройство не обеспечивает высокого качества подстройки при ({юрмировании частотно10 модулированных сигналов с большой базой (база сигнала равна произведению его полосы на длительность) и имеет ограниченную полосу синхронизации относительно требуемого закона However, the known device does not provide a high quality of adjustment with ({the setting of frequency-10 modulated signals with a large base (the signal base is equal to the product of its band by the duration) and has a limited synchronization band relative to the required law
