All planar structures are represented by a strike line and dip angle. 一切平面构造均可用向线和倾斜角来表示。
The biggest problem is calculating the seabed slope angle of the unknown seabed. 而对未知海底的倾斜角求解问题是解决波束角效应的难点之一。
When a position gyro is used in the pitch plane the missile is usually launched at a set elevation. 当位置陀螺用在俯仰通道上的时候，导弹通常以一个设定的仰角发射。
Back at the lab, technicians assign the frames latitude, longitude and elevation coordinates from U.S.Geological Survey ground references and scan dozens of frames into a computer. 回到实验室，技术人员会参考美国地质调查所的地面资料，指出画面拍摄的经纬度与仰角坐标，并把数十张画面扫描到电脑里。
