It is shown that sum-difference amplitude-comparison monopulse is in fact an effective search method for a single target with azimuth in the vicinity of the peak the sum beam.
研究表明，传统单脉冲和差比幅法实际上是一种搜索方位在和波束最大点附近的单目标的有效方法。
The azimuth can be determined by fixing two GPS in a certain distance along the longitudinal vector and making a carrier phase double difference between them.
如果沿载体纵向相距一定距离放置两个GPS天线，则在载体上两个天线载波相位之间求差可确定载体的方位。
Different azimuth of crown of a tree, there was no difference in disease proportion as the whole, but the upper was lighter than the lower.
树冠不同方位病叶率相差不大，树冠上部叶片发病轻于下部。
