A method is presented to calculate the impulse respone of a spherically focused transducer which generates a signal and then receives the reflection of the signal from a rigid surface. Results of calculations are shown in order to illustrate the effects of varying the focal length and the aperture. These results suggest a method for empirical determination of effective values of the governing parameters of the transducer impulse response.
