earth curvature

The latter first research the properties of earth curvature and atmospheric refraction, then estimate the altitude by increasing the radius of the earth.

后者充分考虑地球曲率以及大气折射的特性，通过增加地球半径来估算目标的高度。

Topographic factors such as hypsography and earth curvature are greatly responsible for remote sensing image distortion.

地形因素,包括地面起伏和地球曲率,是造成航空数字遥感影像变形的主要原因之一.

An Item of Earth Curvature Rectification That Should Be Replenished of Wild A10

WILD-A10仪地球曲率校正应补充的一项

Based on the simulation, the earth curvature's influence to target echo and surface clutter power was analyzed quantitatively.

在仿真实验的基础上，分析了地球曲率对目标回波和面杂波功率的影响。

Theoretical calculation shows that the sun phase angle, observation distance and the brightness magnitude of the targeted satellite change significantly because of no earth curvature effect and large separation distance in position.

仿真计算表明，天基观测由于不受地球曲率影响，且观测几何拉开，太阳相位角、观测距离变化范围较大，因此目标卫星视星等变化范围较大。

Influence of the Earth Curvature in the Airborne Radar's Function Simulation
