This final report consists of eleven sections. The first is a list of the problems which were considered during the period of performance. Second is the Introduction. Third is the paper Beam-forming applications of polynomials with restricted coefficients, which has appeared in the Proceedings of the 1987 NATO ASI on Electromagnetics Kluwer Academic Publishers, 1991. Fourth is the paper An ideal omnidirectional transmitting array, and optimal peak factor array, for less than half-wavelength spacing. Fifth is the paper A random variables method for determining the poles of radar targets. Sixth is the paper A computationally efficient notch filter. Seventh is the paper A new rational approximation to digital filters. Eighth is the paper Concerning Pronys method. Ninth is the paper Barker sequences and Littlewoods two-sided conjectures on polynomials with plus or minus 1 coefficients. Tenth is the paper A note on rational approximations to the Fresnel integral.
