Abstract : It is the purpose of the present contract to obtain a theoretical understanding of the excitation of the scalar feed by sources suitable for two and four horn monopulse applications. Initially two parallel investigations are underway. The first involves determining natural modes for the conical horn geometry of the scalar feed satisfying appropriate impedance boundary conditions and the coupling from various sources to these modes. The second investigation is based on the development of a digital computer program for solving the integral form of Maxwell's equations directly for radiation from the scalar feed structure as a metallic body of revolution.
