Abstract(in English) | Like a RADAR and SONAR,application of spread spectrum technology for medical ultrasound imager takes form of encoded waveform transmission combined with correlation receiver.Due to inherent nonlinear property of signal transmission acoustic medium,signal waveform distortion is inavoidable which causes decorrelation as well as time-siderobe rising.A practical computer simulation of nonlinearity in propagation enabled precise estimation of this phenomena and code design optimization against nonlimear propagation.Apodized chirp signal is supported the best choice also in this enviroment,in terms of time siderobe requirement in medical ultrasound imagery.Combination of dual polarity transmission vastly reduces time siderobe due to nonlinear propagation. |
