The error in measuring the characteristics of anechoic chambers by plotting radiation patterns is analyzed. It is shown that the result of measurements is an estimate of the local reflectivity with errors, due to the nonuniqueness of the solutions of the initial measurement equations and the discreteness of the measurement data obtained. Ways of reducing the errors in estimating the local and integral reflectivities are proposed.
