In this paper the uncertainty component of a multisensor microwave
reflectometer dependent on mutual reflections between sensors is
described. One-line and two-lines arrangement of the set of sensor
localization are considered. Adjacent sensors influence each other. The
mathematical model of signal flow graphs of such a system was
developed. The set of linear algebraic equations incorporating main
reflections between sensors was worked out. The least squares method or
Kalman filter for averaging the sensor signals with random distortions is
used. The uncertainty of measuring the power by the multi-sensor
reflectometer is estimated. The obtained results are discussed. The
described methods of the uncertainty evaluation can be applied to
automation of the multi-sensor reflectometer and in other multivariable
measurements.
