Zusammenfassung:Computing device, software and method for calibrating pilot and drive signals of a marine seismic source array using measured data. The method includes receiving a source array geometry and a model of the source array; estimating an initial overall response of the source array based on numerical simulations, the model of the source array, and the source array geometry; generating the pilot and drive signals for the source array based on the initial overall response; determining individual responses of the source elements, which form the source array, based on the source array geometry, the model of the source array, and first measured data; calculating an actual overall response of the source array based on the pilot and drive signals, the model of the source array and second measured data; and adjusting the pilot and drive signals based on the actual overall response of the source array.
