WebR2 = re2 + (re + H)2 - 2re(re + H)· cos α (4) Calculation of the Down Range Under the assumption that the Earth is a sphere, the section of the circumference of the Earth can be calculated with help of a simple ratio … WebWhile the latitude adds, the changes of the earth’s mean redius of curvature is linear. When the latitude adds 0.1 degree, the earth’s mean redius of curvature adds nearly 100 meters . So the earth’s mean redius of curvature changes very much along with latitude. How much influence is brought on sporneborne InSAR height survey by so much change?

This equation as'sumes standard propagation conditions and radar capability of target detection at this range. ... WebThus viewing due north or south the radius of curvature is roughly linear in a small magnitude term proportional to the latitude's squared cosine. The maximal radius of curvature is at either pole with r ≈ a (1 + ½ e 2); the minimal radius at the Equator with r ≈ a (1 - e 2). For the WGS84 ellipsoid e 2 = 0.00669437999013, roughly 1 part ... newport oregon whale watching
