A new formulation is presented for the prediction of the signals transmitted by a rectangular acoustic source, and detected by a finite-sized rectangular receiver. This problem is encountered in measurements where the receiver is of a finite size compared to the shortest wavelength emitted by the source. The paper examines this problem theoretically, and a new formulation is presented in which the geometrical aspects are considered in some detail. The result is a simplified approach, in which the overall impulse response can be obtained from a combination of certain contributions defined geometrically. Theoretical field predictions are compared to experimental measurements for ultrasonic signals radiated into air, to demonstrate the usefulness of the approach.
