The evaluation of jet noise source distributions as obtained by using the polar correlation technique is discussed. The accuracy with which this, or any other, technique can measure a jet noise source distribution is limited by the analytical model used to describe the source distribution and the statistical estimate which can be made of the randomly fluctuating source strengths. Both these problems are considered and criteria are developed for the accuracy of source location data in terms of the measurement parameters. © 1982.
