亮度调制 meaning in Chinese

intensification modulation; intensity modulation

The key point of the research is that , although the detection performance of sonar signal processing subsystem has been optimized , there is still a space of improvement which can be achieved by the means of display and post - processing
本文的设计思想是在声纳信号处理系统的基础上，通过声纳显示技术和亮度调制信号的检测技术，进一步提高信噪比，改善声纳检测性能。
Ultrasonic bio - instrumentation has several display modes used in medicinal field now , such as b - mode and m - mode , etc . b - mode uses the modulated brightness to represent the amplitudes of ultrasonic echoes , and the coordinates in the formed profiles correspond to positions of ultrasonic beam scans one by one
B型显示是用亮度调制来显示回波脉冲幅度，显示的横轴和纵轴与声束扫描的位置一一对应，形成超声切面图像。
