摘要
The invention relates to methods for studying interplanetary plasma in near-Earth space. The purpose of the invention is to obtain, in addition to the usual parameters determined by the interplanetary plasma radio transmission method, the distance L from the Earth to the region of increased turbulence of the solar wind and perpendicular to the direction of the Moon. The invention relates to radar and communication, namely to radio physical interplanetary plasma studies. in near-Earth space, designed to control the region of increased turbulence of the solar wind at the outer boundary of the Earth’s magnetosphere and can be used l diagnosing disturbances of the solar wind on the Earth -Luna. The aim of the invention is to measure the distance to the region of increased turbulence of the solar wind and the perpendicular to the ray of sight of the component of the solar wind speed. The component of the solar wind velocity Vt in this region on the Earth-Moon route. This is ensured by the fact that radio signals are emitted from the surface of the Earth in the direction of the Moon in the range of frequencies at which the period of libration fluctuations of the intensity of signals reflected from the Moon exceeds the arrival time of the moon radio echo. The intensity of the lunar radio echo is measured, its autocorrelation function is calculated, its fluctuations are determined, and L and Vi are determined by the formulas: LD - 0.5 С С Т0 Vi -57- (D - 0.5 С TO) / fD where D is the distance from Earth to the Moon; C is the speed of light; T0 is the ACF side maximum argument; Ar is the width of the lateral maximum of the ACF at 0.5; f is the frequency of the emitted radio signal. 1 il. CO FIG. 1 shows the structural electrical circuit of the device. The device contains a transmitter 1, antenna 2, receiver 3, antenna 4, quadratic detector 5, correlometer 6, unit 7, synchronization. The essence of the invention is as follows. Radio signals are emitted from the Earth in the direction of the Moon, radio signals reflected from the Moon are received, their autocorrelation function (ACF) of intensity fluctuations is measured. ACF intensity fluctuations reflected from the moon by radio signals of the ground VI
