Criteria for negligible smallness of random and systematic components of measurement errors

The problem of numerical values of criteria for negligible smallness of random and (residual) systematic components of the total measurement error is investigated within the framework of a well-known approch to estimation of measurement errors (GOST 8.207-76). Various aspects of this problem are analyzed. A correct procedure for obtaining the limiting values of the relative error of estimation is presented. Estimation errors — corresponding to several values of criteria for negligible smallness recommended in the literature are compared.

Investigation of systematic errors and means of reducing them in measuring radar characteristics

This report is concerned with a systematic error in measuring radar characteristics, due to the inadequacy of the free space measuring condition. In particular, we consider the effect of the underlying surface on effective scattering area (ESA) measurements, for the conditions of an open polygon. A method is proposed for reducing this influence. Translated from Izmeritel'naya Tekhnika, No. 7, pp. 45–47, July, 1995.     

Representing measured quantities and measurement errors as fuzzy variables

In order to describe measured quantities and measurement errors as fuzzy variables, two forms are considered of simplified assignment functions in the form of trapezia with rectilinear and curvilinear sides. The expressions for the systematic and random error components then correspond to the existing standardization documentation. The mathematical processing programs for measurements operate with rules for acting with fuzzy variables and have potential capacity for providing their own metrological documentation. Comparative numerical examples are given. __________ Translated from Izmeritel’naya Tekhnika, No. 2, pp. 3–8, February, 2007.
