    • Abstract
  • In order to introduce the digital encoded technology to the seismic detection,the author studied coded excitation digital simulation and grasped the rules and characters of coded excitation,which is based on the basic coded excitation principle.By modulation launching of coded excitation signal,the author also did simulation research on pulse compression of received signal.Furthermore,the author processed pulse compression with 13 bit signal excitation transducer with one to five units code element(by launching of 13 bit signal excitation transducer with one to five units code element).The author did the power spectrum analyses and analyzed the influence on different excitation signal and its pulse compression result by transducer.
