The Design of Complex Structure Echo Signal Simulator

WANG Run-tian, ZHU Qun-feng, TONG Xin(Shanghai Acoustics Laboratory, Chinese Academy of Sciences, Shanghai 200032, China)  
A complex structure signal simulator designed by DDS technique is introduced. It can simulate several kinds of strata echo waves or complex structure signals. The DDS technique is mainly described, and the basic principle and the composition of the signal simulator are introduced with a complex structure strata echo signal. The design procedure introduced in the paper is of universal signification.
