A METHOD FOR THE PREDICTION OF THE FARFIELD FROM NEARFIELD AMPLITUDE MEASUREMENTS OF A COHERENT SOUND FIELD.
Abstract
A method is presented for the prediction of the farfield from nearfield measurements of the amplitude alone of a coherent field. The method is based on a finite series wavefunction expansion for the pressure amplitude in the field. It is shown that with the expansion specialized for a coherent field there is a vast improvement over a previous general method for partially coherent fields. (Author)
