Abstract: This paper presents the modeling of air targets of proximity fuzes using experimental data. The target model consists of many scattering points. The determination of their numbers, positions relative to the gravi?ty center of the targets and cross sections are directly based on the analysis of a great number of scattering data obtained from sxperiments. The com?bined model has been established adopting the methods of non-linears ystem identification and interpolation. VVlien the intersection conditions of the fu?ze and the target are given, the scattering signal can be obtained using the combined model. Statistical tests show that the fitting precision of the mo- del is satisfactory and that it can well be used in fuze design and system si?mulation.
