- Abstract
A method is considered for measuring the radiation levels of extended spatially uncorrelated sound sources in the near field in the case of their imprecise positioning with respect to the measurement system-a linear antenna array. An algorithm is proposed for synthesizing the vector of weight coefficients ensuring the given value of methodological measurement error under maximum suppression of external noise. Examples are given of numerical modeling and experimental testing of the method in natural conditions.
