Ultrasound-assisted gene delivery is associated with the parameters of ultrasound exposure, such as mechanical index, pulse repetition frequency, time of exposure, and so on.
超声的此种特性，与超声的照射条件，如机械指数、脉冲重复频率、照射时间等有关。
So, the modulation of irregular pulse repetition interval may be employed in FCP that the randomization of signal modulation would be obtained in both time and frequency domains.
因此，若将重复周期参差调制方式融合到频率编码信号中，可使信号具备时-频调制双重随机性。
Next, it introduces the extraction method of the time-domain parameters such as pulse width, pulse repetition rate and pulse range.
接下来介绍了雷达脉冲的宽度、重复间隔和幅度等时域参数提取方法。
