In this chapter we have discussed the more important of the high frequency methods for predicting the RCS of simple structures. The great utility of these theories is that in the high frequency region, the target elements scatter the incident wave independently of one another. This makes it possible to assemble a collection of relatively simple shapes, such as flat plates, cylinders, and spheroids to model a complicated target. The analytical high-frequency formulas are relatively easy to derive for specific geometries, and we only need to sum the individual contributions coherently to obtain the total RCS of the target.
