Description

Изобретение.относитс  к измерительной технике .The invention relates to measurement technology.

Известен радиолокационный способ измерени  скорости вращени  путем облучени  контролируемого объекта и анализа отраженного излучени , в котором в отраженном излучении определ ют интервал смещений любой частоты, обусловленный допплеровским сдвигом .A radar method is known for measuring the rotational speed by irradiating a controlled object and analyzing the reflected radiation, in which the interval of displacements of any frequency due to Doppler shift is determined in the reflected radiation.

Полна  щирина допплеровского смещени , обусловленного вращением, не может быть надежно измерена, поскольку амплитуды сигналов стрем тс  к нулю при приближении частот к интересующим крайним значени м. Кроме того, непосредственно измер емой величиной  вл етс  линейна  скорость точек контролируемого объекта, пропорциональна  его радиусу.The full width of the Doppler shift due to rotation cannot be reliably measured, because the amplitudes of the signals tend to zero as the frequencies approach the extreme values of interest. In addition, the directly measured value is the linear velocity of the points of the object being monitored, which is proportional to its radius.

Предложенный способ отличаетс  тем, что с целью повыщени  точности в отраженном излучении определ ют интервалы частоты между гармониками, обусловленными микроперовност ми формы и неоднородпост ми материала объекта при облучении монохроматической волной микроволнового диапазона.The proposed method is characterized in that in order to increase the accuracy in the reflected radiation, frequency intervals are determined between the harmonics caused by the microperme forms and the inhomogeneities of the material of the object when irradiated with a monochromatic microwave wave.

На чертеже показана схема устройства, реализующего продложенный способ.The drawing shows a diagram of the device that implements the proposed method.

Генератор непрерывных монохроматических колебаний 1 через антенну 2 облучает контролируемый объект 3. Отраженное излучение воспринимаетс  приемной антенной 4, проходит детектор 5, усилитель низких частот 6 и анализатор гармоник низких частот 7, выдел ющий контролируемую частоту. Самопишущий частотомер 8 непрерывно регистрирует скорость вращени  объекта.A generator of continuous monochromatic oscillations 1 through the antenna 2 irradiates the monitored object 3. The reflected radiation is perceived by the receiving antenna 4, the detector 5 passes, the low frequency amplifier 6 and the low frequency harmonic analyzer 7, which separates the controlled frequency. Recording frequency counter 8 continuously records the rotational speed of the object.
