ASPECT AND DEVIATION ANGLE
Abstract
The purpose of this paper is twofold: first, an attempt is made to define aspect angle and deviation angle in a logical and acceptable manner; second, a graphical calculator is supplied in the hope that it will make the calculation of these angles so simple that the definitions will be use without unnecessary approximations. When a target is being observed by some means, it frequently happens that the target is associated with some vector of importance, as for example, its heading or velocity. In this case the observer is very often interested in an aspect angle which is the angle between the vector of interest and the direction of propagation of whatever wave is used for the observation (e.g., light, radio, sound, etc.). There are three angles associated with this aspect angle which can normally be measured by an observer with ease; the graphs given can then be used to find the true aspect angle.
