多普勒展宽 meaning in Chinese

doppler broadening

It is based on a proper decomposition of the ship motion in horizontal and vertical components . proper imaging intervals in order to obtain high quality ship images are selected using the estimated rotating angular velocity and doppler extension
它将转动分量作了水平、垂直分解,估计出旋转角速度和多普勒展宽,并借助于它们选择最优成像时间段以得到较高质量的舰船图像。
Rtce is based on forecasting the inherent vulnerabilities to propagation of hf time - varying channel , including multipath delay , doppler spread , selective fading , interference , so this paper also introduces characteristics of hf channel in the beginning . familiar rtce systems all adopt envelope method that bello brought forward
实时选频技术是基于对短波电离层时变信道固有的不利于电波传播的各种因素，包括信道的多径展宽、多普勒展宽、选择性衰落、噪声干扰等的预测的基础上实现的，所以在开篇对短波信道的特点进行了详细的介绍。
