Для решения задачи об определении траектории светового луча в зависимости от первоначального направления распространения используется принцип Ферма. Для вычисления времени полета фотона к объекту, зная его координаты, дополнительно вводится условие светоподобности интервала для распространения света.</p><p>Полученная траектория световой частицы является дугой окружности. Для малой области около источника траектория фотона совпадает с параболической траекторией классической корпускулы. Выведено равенство для направления, в котором посылается радиосигнал. Фактическое местоположение объекта находится не в направлении начального движения фотона, а несколько ниже. Вычислена величина угла гравитационного преломления для близко расположенного покоящегося объекта. Чем объект дальше в «горизонтальном» направлении, тем угол преломления больше. Найдено время полета светового сигнала к объекту. Сигнал, излучаемый в направлении, которое образует острый угол с направлением ускорения, опережает радиосигнал в инерциальной системе отсчета. Поэтому для близкого объекта, расположенного выше источника излучения, вычисленное время задержки Шапиро отрицательно. Вычислены также координаты удаленного объекта.</p><p>Совокупность полученных равенств полностью определяет радиолокационный метод. Выведенные равенства возможно допускают экспериментальную проверку.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of this work is to generalize the radar method known for the inertial frame of reference to the case of a uniformly accelerated frame of reference.</p><p>The derivation of the corresponding formulas is based on the standard for the theory of relativity metric of a uniformly accelerated Möller frame of reference without applying any space-time transformation between some auxiliary inertial frame and the accelerated frame. To solve the problem of determining the trajectory of a light beam, depending on the initial direction of propagation, Fermat’s principle is used. To calculate the flight time of a photon to an object, knowing its coordinates, the condition of the light-likeness of the interval for the propagation of light is additionally introduced.</p><p>The resulting trajectory of the light particle is an arc of a circle. For a small area near the source, the photon trajectory coincides with the parabolic trajectory of a classical corpuscle. An equation has been derived for the direction in which the radio signal is sent. The actual location of the object is not in the direction of the initial motion of the photon, but somewhat lower. The value of the angle of gravitational refraction for a closely spaced resting object is calculated. The further the object is in the “horizontal” direction, the greater the angle of refraction. The flight time of the light signal to the object is found. The signal emitted in the direction that forms an acute angle with the direction of acceleration leads the radio signal in the inertial frame of reference. Therefore, for a close object located above the radiation source, the calculated Shapiro delay time is negative. The coordinates of the remote object are also calculated.</p><p>The totality of the obtained equalities completely determines the radar method. The resulting equalities, perhaps, allow for experimental verification.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>принцип Ферма</kwd><kwd>модель Пуанкаре в верхней полуплоскости</kwd><kwd>пространство Лобачевского</kwd><kwd>гравитационное преломление</kwd><kwd>задержка Шапиро</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Fermat’s principle</kwd><kwd>Poincaré half-plane model</kwd><kwd>hyperbolic geometry</kwd><kwd>gravitational refraction</kwd><kwd>Shapiro delay</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">Фок В.
