There are four math concepts outlined in this chapter (all higher-level math above algebra is explained). The first is dB math-required for the presentation of propagation-theory formulas. The second is spherical trigonometry-to develop EW engagement models, you have to be able to rotate vectors in space using spherical trig. The third is the Poisson equation-in order that you will be able to determine the probabilities required for the design of emulation devices. The fourth is digitization - because almost everything is digital these days.
