Use of cluster analysis method to increase the efficiency and accuracy of radar data processing
The article presents a range of solutions to improve the efficiency and accuracy of multiradar data processing using cluster analysis method. For this purpose commend to use cluster analysis method, based on which authors made an improvement for the classical abnormal measurement rejection algorithm and consider a possibility to implement a multithread processing of radar data.
Experience in constructing and investigating the accuracy of a local spatial trilateration network
In [2], the feasibility of developing spatial trilateration networks for the study of deformations of the earth's surface at geodynamic polygons is theoretically justified.
About the precalculation of the accuracy of building geodetic networks
The construction of geodetic construction nets is traditionally produced according to the deductive principle of the transition from the general to the particular. As noted in [1], each previous step should create a reliable control of the construction of the subsequent one and do not affect in a tangible way the accuracy of determining the points of the newly constructed grid.
Estimating the accuracy of the two-group adjustment of the correlated quantities
The article [2] is a review of my article [3], it notes that the formulas we have built up are correct, but their conclusion is guilty of "gross errors, ignorance of the elementary rules of matrix algebra," etc.
The accuracy of extrapolation of trends of polynomials approximated by the first three degrees
When analyzing time series to identify trends in the development of the phenomenon, for example, the draft of the structure, trends based on the results of observations are used.
Study of the accuracy of determining the azimuth by the hour angle of the sun by visual methods
The methods of astronomical definitions of the geographic coordinates of the point and the azimuth of the direction are based on measuring the horizontal coordinates of the luminaries at fixed times of a particular time counting system. The programs of the methods introduced into production are designed for the most favorable conditions for observations of luminaries, when the influence on the result of the measurement errors and the coordinates of the point is minimal.
The comparison researches of accuracy of the automated definition and the account of an anomalous vertical refraction by a santilometr, a videotheodolite and a digital level
It is proved in the article, that accuracy of the modern automated methods of definition of an anomalous vertical refraction to the devices equipped with CCD - sensor, makes: 1. by the videotheodolite TM3000V - 0,67”; 2. by the level SDL-30 - 0,31mm at length at distance about 100m. The offers concerning increase of accuracy of definition of a refraction are made.
Determination of current setting time in inductive load of voltage-to-current converter under non-harmonic influence
The paper presents analysis of problems dealing with the determination of the current setting time in the inductive component of the complex load of Voltage-to-current (VTC) converter under non-harmonic input influence. There is showed the change in the transient response and in the current setting time of the inductor on changing the VTC converter and complex load parameters. Expression to determine the current setting time of complex load of VTC converter at given level of dynamic error is presented.
Ensuring the stability of voltage-to-current converter with complex load
In this paper, the method of determining the stability of the voltage-to-current converter (VCC) with complex load, which is built on the DC amplifier with a deep negative feedback (NFB) by current. The feedback signal is formed on precise resistor, which is connected in series with an inductive load. The deep feedback and complex load can cause a violation of the stability of the VCC across the whole dynamic range of operation.
