Abstract
To reduce the cost of field tests of the ballistic objects (BO) simulators reflection properties, it is advisable to develop a model and algorithm for calculation of the radar objects effective surface scattering. As a simulator of ballistic objects a complex radar reflector, made of a lossfree dielectric is chosen. It looks like a spherical Luneburg lens with a coating of high-conductivity alloy as well as a truncated cone, disk, and cylindrical elements. The stages of aperture version of reflection from the inner surface of the Luneburg lens are proposed. A physical model of the reflection on the elements of design and the technique of modeling with a calculation algorithm of the effective surface scattering are developed. The algorithm of calculation of the ballistic objects resonance effective surface scattering is worked out. This algorithm is presented in a graphical form. The interface of the computing complex is presented. As a simulator of ballistic object we selected a complex radar reflector, made of a lossfree dielectric sphere with a coating of high-conductivity alloy as well as of a truncated cone, disk, and cylindrical elements. The comparative indicatrices of ballistic objects simulator are presented. The conclusion on the comparative analysis of the results of measurements in situ and modeling results is made. The examples of numerical calculations of the ESR of the head part of the BO simulator with increased ESR and increased all-aspect view are given. The options of the BO simulator head parts with increased ESR and increased all-aspect view with optimal placement of radar dielectric reflector and a corner unit with sectional placement of dielectric reflectors are analyzed.
