1) carrier-to-noise ratio
载波信号噪声比
2) carrier-noise ratio
载波噪声比
3) signal-to-noise ratio
信号噪声比
1.
To increase signal-to-noise ratio(SNR) of medical ultrasound image,a frequency-modulated(FM) ultrasound transmitted imaging method is developed,where a weighted linear FM ultrasound is transmitted to enhance the emission energy without increasing the emission ultrasound pressure,and the image signal is formed by the demodulated ultrasound.
为了提高医学超声图像的信号噪声比,研究了调频超声发射的成像方法。
4) signal to noise ratio(SNR)
信号/噪声比
5) noise-signal ratio
噪声信号比
6) signal-to-clutter-noise ratio
信号杂波噪声比(SCNR)
补充资料：载波
已调波中的高频波。将信息调制在等幅的高频振荡波或脉冲波上，才能通过各种不同媒介传送到远方去。由于高频波或脉冲波上载有信息，故名。
