Abstract

Система радиосвязи Земля-Луна-Земля, включающая в себя земной передатчик радиоизлучения сантиметрового диапазона длин волн с антенной, направленной на Луну, и земной приемник отраженного от Луны радиоизлучения с антенной, также направленной на Луну, отличающаяся тем, что в центре видимой с Земли лунной поверхности в круге диаметром не более 200 км размещено зеркало для отражения радиоизлучений, которое выполнено в виде круга диаметром не более 21 км из уголковых отражателей, коэффициент отражения которых не менее 0,7, а угол расхождения отраженного радиолуча γравен 0,9°, причем земной передатчик размещен так, чтобы при вращении Земли вокруг своей оси он оказался в зоне, в которой его включают для связи и которая образована квадратным основанием условного четырехгранного телесного угла с вершиной на зеркале, осью телесного угла является ось Земля-Луна, а угол θ каждой плоскости грани телесного угла с его осью определен неравенством 0,24°≤θ≤0,26°, а условие приема на Земле отраженного от Луны эхосигнала определяется неравенством,где Ки К- соответственно коэффициенты отражения радиоизлучения от зеркала и от лунной поверхности, S- площадь зеркала, S- площадь лунной поверхности, отражение от которой достигает Земли.The Earth-Moon-Earth radio communication system, including an earth centimeter radio transmitter with an antenna directed to the Moon, and an earth receiver of radio radiation reflected from the Moon with an antenna also directed to the Moon, characterized in that in the center of the lunar visible from the Earth surface in a circle with a diameter of not more than 200 km there is a mirror for reflecting radio emissions, which is made in the form of a circle with a diameter of not more than 21 km from corner reflectors, the reflection coefficient of which is not less than 0.7, and the angle of divergence radial beam γ equal to 0.9 °, and the Earth transmitter is placed so that when the Earth rotates around its axis, it will be in the zone in which it is turned on for communication and which is formed by the square base of the conditional tetrahedral solid angle with the vertex on the mirror, the axis of the solid angle is the Earth-Moon axis, and the angle θ of each plane of the face of the solid angle with its axis is determined by the inequality 0.24 ° ≤θ≤0.26 °, and the condition for the reception of an echo signal reflected from the Moon on the Earth is determined by the inequality, where Ki Ki are the reflection coefficients respectively ioizlucheniya from the mirror and from the lunar surface, S- surface area, S- lunar surface area, which reaches the reflection from the Earth.
