WebThe height error is the difference between the apparent height, which is the height calculated assuming no refraction, and the true target height. To calculate the apparent height, use the range2height function with the true Earth radius. Note that the detected height errors match the predicted height errors well.

WebThe apparent depth h i depends on the angle at which you view the image. For a view from above (the so-called “normal” view), we can approximate the refraction angle θ to be small, and replace sin θ in Snell’s law by tan θ. With this approximation, you can use the triangles Δ O P R and Δ O Q R to show that the apparent depth is given by WebFor a view from above (the so-called “normal” view), we can approximate the refraction angle θ to be small, and replace sin θ in Snell’s law by tan θ.
