Abstract: Предложен новый подход для радиометрической оценки состава и свойств физических и биологических объектов различной структуры за счет спектрального анализа интенсивности их собственных слабых радиотепловых излучений. Рассмотрена функциональная схема устройства, принцип и алгоритм обработки сигналов. Показано, что при данном способе оценки на результаты контроля параметров объектов не влияют аддитивная и мультипликативная погрешности радиометрического устройства.
Description: Radiometric measurement receivers are widely used in various fields of science and technology. With this apparatus we can evaluate the composition and physical and biological properties of objects by measuring the energy spectrum in a certain range. However, the measurement methods and apparatus for converting narrowband slope do not allow estimating the variance of the radio spectrum by the value of the output voltage reliably due to instability of measurement receiver when tuning to a different frequency, the complexity of creating the reference noise generator with a uniform spectral density over a wide range of microwave frequencies, impossibility of calibrated attenuation of the radiation received at the input of the antenna and the applicator, etc. From the above it follows that the parameters for the study of physical and biological objects with different structures by measuring the intensity of the energy spectrum of their own weak radio emission requires a new approach to solving this problem, allowing to provide greater information capacity, sensitivity and precision equipment. A new approach is required for radiometric estimation of the composition and properties of the physical and biological objects of different structure due to the spectral analysis of the intensity of their own weak radio thermal radiation. The proposed solution makes it possible to determine the composition and properties of the objects of study by measuring and recording the energy spectrum of weak radio signals, and the results of the evaluation will not be affected by additive and multiplicative errors of radio receiver channel. The impact of measurement of intrinsic noise of the antenna and receiver channel on the result is also excluded. The proposed solution makes it possible to determine the composition and properties of the objects of study by measuring and recording the energy spectrum of weak radio signals, while on the results of the evaluation will not affect additive and multiplicative errors radio receiver channel. Excludes the impact on the result of measurement of intrinsic noise antenna and receiver channel.
