1. A types of level omnidirectional arrays of antenna is designed and studied according to the characteristics of short-wave. 根据短波传输的特点设计并研究了一种水平极化的全向振子阵。
2. We propose a new mapping method based on the fuzzy system theory to obtain a 3D ground coordinate from a 2D omnidirectional image. 本文提出一个基于模糊系统理论的影像转换方法,由2D影像取得3D场地座标讯息。
3. It introduces a new method-Omnidirectional M-mode echocardiography, which can detect the dynamic information from sequential echocardiography. 介绍一种从超声心动图序列图像中提取一种新运动信息的新方法——全方向M型心动图。
