Условием для констатации факта нарушения границы запретной зоны считается нахождение БЛА в ее пределах в течение заданного времени. Проведено обоснование математической модели для проведения исследований в виде линеаризованного векторного стохастического уравнения. Задача решается на основе применения теории марковских процессов случайной структуры с поглощением реализаций на границе заданной области. Особенностью данного подхода является одновременное рассмотрение двух плотностей вероятности распределения фазовых координат, характеризующих граничные условия. При этом решаются две системы уравнений для вероятностных моментов: с учетом поглощения реализаций и без учета данного поглощения соответственно. Рассматривается вероятность попадания объекта в заданную область и невыход из нее в течение времени, необходимого для фиксации БЛА в запретной зоне.</p></abstract><trans-abstract xml:lang="en"><p>The probabilistic analysis of crossing by an unmanned aerial vehicle (UAV) of the boundary of the no-fly area is solved. Condition of stating of the fact of the violation of the boundary of the restricted area is to stand of UAV within the area during a specified time. The substantiation of the mathematical model to research through linearized vector stochastic equation is carried out. The problem is solved by applying the theory of Markov processes of random structure with absorption of realizations at the boundary of a given area. Particularity of the approach is the contemporaneously consideration of two probability densities of the distribution of phase coordinates that describe the boundary conditions. In this case, two equations systems are solved for probabilistic moments: taking into account the absorption of realizations and without taking into account the absorption. The probability of an object gets into specified area and do not leave one during the time that necessary to notice the unmanned aerial vehicle at the restricted area.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>беспилотный летательный аппарат</kwd><kwd>граница</kwd><kwd>структура</kwd><kwd>плотность вероятности</kwd><kwd>уравнения для моментов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>unmanned aerial vehicle</kwd><kwd>boundary</kwd><kwd>structure</kwd><kwd>probability density</kwd><kwd>equations for moments</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Беспилотные летательные аппараты [Электронный ресурс]. – Режим доступа: http://geoportal.by/index/bespilotnye_letatelnye_apparaty/0–434/.</mixed-citation><mixed-citation xml:lang="en">Unmanned aerial vehicles [Electronic resource]. – Access mode:  http://geoportal.by/index/bespilotnye_letatelnye_apparaty/0–434/.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Семейство беспилотных авиационных комплексов видео-мониторинга местности «Бусел», «Бусел М», «Бусел М50» [Электронный ресурс]. – Режим доступа: http://uavbusel.by/catalog.html/.</mixed-citation><mixed-citation xml:lang="en">The family of unmanned aerial systems for video monitoring of the area «Busel», «Busel M», «Busel M50» [Electronic resource]. – Access mode: http://uavbusel.by/catalog.html/.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Roos, J.
