    摘要: A Sonar decoy system receives an interrogating pulse from an energy sourcend then distorts, elongates, amplifies, and retransmits the pulse to simulate an echo of that pulse rebounding from the various reflecting surfaces of a moving submarine. To refine the allusion of an actual echo, a portion of the pulse signal is circulated and recirculated through a delay line several times, and then reinserted into the outgoing signal to contribute random additions to and phase cancellations of the various frequency components of the signal.
