При этом для решения задачи наведения количество требуемых навигационных позиций уменьшается на одну по сравнению с классическим методом разностно-дальномерной навигации. Однако в алгоритмах наведения все же требуется иметь некоторую оценку дальности наводимого объекта от центра базы, способы получения которой рассмотрены в работе.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, a method for estimating the distance to the object guided along a hyperbola to a target using a bistatic hyperbolic navigation system on a plane is given. At the same time, to solve the guidance problem, the number of required navigation positions is reduced by one in comparison with the classical method of hyperbolic navigation. However, in the guidance algorithms, it is still required to estimate the distance of the targeted object from the center of the base, the methods of obtaining which are considered in the work.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>разностно-дальномерная навигация</kwd><kwd>бистатическая система</kwd><kwd>гипербола положения</kwd><kwd>измерение доплеровского смещения частоты</kwd><kwd>измерение дальности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hyperbolic navigation</kwd><kwd>bistatic navigation</kwd><kwd>position hyperbola</kwd><kwd>Doppler frequency shift</kwd><kwd>range measurement</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">Groves, P.
