In response to reader requests, this is the first of a two part series on spherical trigonometry (trig), an important tool in understanding electronic-warfare (EW) engagements and the operation of some types of EW equipment. This month, we will run through the basic relationships in spherical triangles. Next month, we will apply spherical trigonometry to several practical EW problems.
The Role of Spherical Trigonometry in EW
Spherical trig is one way to deal with three-dimensional problems and has the advantage that it deals with spatial relationships from the "point of view" of sensors. F...
