Abstract

Спектр выходного сигнала управляемого акустического источника с качающейся частотой на данной частоте может управляться путем приравнивания скорости изменения частоты к желаемому спектру мощности выходного сигнала, деленному на квадрат огибающей амплитуды выходного сигнала источника, при этом обе величины измеряют в момент времени после начала его частотного свипа, когда частота свипа проходит через данную частоту. Система и способ также могут быть использованы для внесения поправки на эффекты распространения вне источника путем деления желаемого спектра на эффект распространения. Способ может быть дополнительно использован для получения спектра выходного сигнала желаемой формы из источника, работающего на максимальной выходной мощности, или для проектирования свипа с минимально возможной длительностью, который будет давать в результате спектр выходного сигнала определенной формы и с определенной амплитудой.
