The problems of designing linear phase FIR digital filters using window functions are discussed. The design of linear phase FIR digital filters using practical non-ideal frequency characteristic models is evaluated. Ladder and raised cosine roll-off, etc. function models are studied. Results show that the design procedure of FIR filters is simplified because of the clear object, direct method, and elimination of the Gibbs phenomenon.

The complex astigmatic wave theory is used to analyse the electromagnetic characteristics of 3-D radome. A number of calculations for the ellipsoidal sandwich radome are performed, and the stereoscopic graphics are constructed. Comparing with the experimental results, it is shown that this method can be used to simplify the optimization designs for some kinds of 3-D radomes.
