THE COMPARATIVE ANALYSIS OF A MULTIPROBE MICROWAVE MULTIMETERS WITH INVOLVEMENT OF PROCESSING BY THE KALMAN FILTERING AND THE LEAST-SQUARES METHODS WITH REGARD FOR RE-REFLECTION OF PROBES
ABSTRACT
An error introduced by re-reflection between sensors into the error of a multiprobe microwave multimeter is dealt with. The spacing between the sensors is appropriate to λw/8 (λw is the waveguide wavelength). This is clearly indicative of the fact that the adjacent sensors tend to be interactant. The one- and two-dimensional placement of sensors is discussed. A mathematical model is constructed using directed graphs. A set of linear algebraic equations is obtained their components taking account of re-reflections between sensors. When evaluating the error power and other parameters determined with a multiprobe microwave multimeter the authors made use of averaging by the least-squares (LSM) achieved allow for a subsequent prompt changeover to the computerized measuring process.
