Limiting Direction Finding Sensitivity of Antenna System for the Direction Finder


M.L. Artemov, A.D. Vinogradov, I.S. Dmitriev, M.Y. Ilyin, G.V. Podshivalova

In article is organized estimation of the direction finding characteristics of the any antenna system for many channel mono-pulse direction finder. The notion for the normalized direction finding sensitivity of the antenna system is made. It notion is does not depend from the noise and speed characteristics of the many channel radio receiver. The expression of limiting (in the sense of borders Kramer-Pao) normalized direction finding sensitivity of the antenna system is received by means the multivariate complex diagram to directivities. This expression allows to value potential sensitivity of the radio direction finder and efficiency the algorithm of direction finding, which supposed to use. The Results of the work are illustrated on example of the four element loop-dipole antenna array. Article contains 2 figures and 12 bibliographic sources of the information.
