ЭЛЕКТРОДИНАМИЧЕСКИЕ МЕТОДЫ СЕЛЕКЦИИ ЦЕЛЕЙ - АНАЛИЗ ГРАДИЕНТОВ

Abstract

We offer a new method for analyzing the electromagnetic field scattered from the objects. The method is based on calculating the field gradients in the incidence and scattering space in a bistatic radar scheme. The analysis of the differences between the real target and artificial jam-producing object showed the high sensitivity and efficiency of the method used, because the topology of the two-dimensional field scattering gradients pattern varies significantly for these two objects. We detected substantial polarization dependence of the scattered field gradients, which together with the topological portraits of the scattered field itself make it possible to find a new approach to the target discrimination. The analysis we did allows us to develop a target detection strategy for an artificial object by the controlled change of the incident and scattered angles (viewing angles) in accordance with the laws obtained in topological portraits of the gradients of electromagnetic fields scattered over a wide angular range from the objects. Findings of the research could be helpful in developing specific strategies of polarization bistatic radiolocation based on the gradient analysis method

Предложен новый метод анализа рассеянного от объектов электромагнитного поля, основанный на расчете градиентов поля в пространстве углов падения и рассеяния в бистатической схеме радиолокации. Показана высокая чувствительность и эффективность метода при анализе различий реальной цели и искусственного помехосоздающего объекта, потому что топология двумерной картины распределения градиентов рассеяния поля существенно различается для этих двух объектов. Обнаружена существенная поляризационная зависимость градиентов рассеянного поля, что в совокупности с топологическими портретами самого рассеянного поля позволяет создать новый подход к селекции целей. Проведенный анализ позволяет разработать стратегию обнаружения цели на фоне искусственного объекта путем управляемого изменения падающих и рассеянных углов (углов наблюдения) в соответствии с полученными закономерностями в топологических портретах градиентов электромагнитных полей, рассеянных в широком угловом диапазоне от объектов. По представленным данным могут быть разработаны конкретные стратегии поляризационной бистатической радиолокации, основанной на градиентном методе анализа
