On the basis of the paraxial approximation it was found that the recorded spatio-temporal signal of the microscope ultrasonic array can be treated as an estimation of the scattering function of visualized objects. It was theoretically established that the scattering functions of the observed inhomogeneities can be used for the interpretation of the generated acoustic images. It is shown that the finite size of the array elements constrains the angular resolution of the method due to smoothing of the measured scattering function. Experimental testing of the proposed method was carried out using the developed prototype microscope with a two-dimensional array of square elements and a polystyrene spherical acoustic lens. It was experimentally confirmed that the spatial resolution of the device corresponds to a theoretical estimate obtained by a classical criterion. The generated images of small flat reflectors with different angles of inclination obtained by means of electronic scanning are presented. It is shown that the output array data set is more informative for the quantitative characterization of the discontinuities than their acoustical images. In particular, on the basis of the obtained estimation of the scattering function it was possible to estimate the angle of inclination of the reflectors.","PeriodicalId":378509,"journal":{"name":"Российский технологический журнал","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121834816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method is based on heavy usage of hardware cores of high-performance programmable logic devices (PLD) for generating harmonic and Gaussian modulating functions in real-time mode. The usage of modulated harmonic series allows tuning parameters of kernel functions both in frequency and time domains, while fine tuning of damping factor of Gaussian function is performed on the base of fixed-point representation of wavelet samples. The proposed hardware generator has a feature allowing to create high-order kernel functions, which is impossible with the approach based on storing coefficients in on-chip memory limited in size. An analysis performed in the article allows calculating a set of integration limits and corresponding damping coefficients for Gaussian modulating function. Implementation on the PLD was performed with combination of existing IP-cores based on CORDIC algorithm and original developed components. Modelling and implementation are performed with Kintex-7 series PLD. Using this approach several high-precision systems were designed. These systems are precision measurement devices for frequency and phase measurements. They also may be used for software-defined radio devices, including pure digital implementation of an input radio-frequency signal. Some examples are also reviewed.","PeriodicalId":378509,"journal":{"name":"Российский технологический журнал","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122093724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their use is regulated by various communication standards. The noise immunity characteristics of their reception against the background of white Gaussian noise are well studied. The article deals with the case when, at the input of the receiver, besides noise, there is a scanning interference. The noise immunity of signal reception with multi-phase shift keying in the presence of noise and scanning interference was analyzed using statistical radio engineering methods. In this case, the interference is represented as a harmonic interference with a frequency varying according to the sawtooth law. Two cases are considered in the study. The first is when the scanning interference does not fall into the zone of the main lobe of the signal spectrum. In this case, its influence is negligible, and it practically does not change the noise immunity of the reception. The second case, when the frequency range of the scan coincides with the zone of the main lobe of the signal spectrum, is more dangerous. The dependences of the probability of a bit error on the deviation frequency of the scanning interference, its intensity and the signal-to-noise ratio are obtained. It is shown that the noise immunity of receiving signals with multi-phase shift keying deteriorates greatly in the presence of scanning interference falling in the region of the main lobe of the spectrum of the useful signal, and this effect is greatly enhanced with increasing signal positionality. When changing the frequency deviation of such interference, its effect on the noise immunity of the M-PSK demodulator changes only slightly. To increase the noise immunity of receiving signals against the background of scanning interference, it is necessary to use interference compensation algorithms, for example, tracking notch filters.","PeriodicalId":378509,"journal":{"name":"Российский технологический журнал","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128157852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
