METHOD FOR DETERMINING LOCATION OF SATELLITE COMMUNICATION EARTH STATION Russian patent published in 2018 - IPC G01S5/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention can be used when searching for and locating the positions of the Earth stations (ES) of satellite communication - the interference sources of trunks with the direct satellite retransmitters (SR) on the geostationary orbit. Simultaneously a sequence of discrete samples of the retransmitted signal levels of the desired ES is recorded, received by the fixed station of the satellite radio and beacon signal of the SR, through which the signal of the desired ES received by the fixed station of the satellite radio is retransmitted. As a result of processing the received sequence programmatically, the groups detailing wavelet coefficients are received that retain or change their values due to the dynamics of the signal levels of the desired ES and the beacon signal of the SR caused by the passage of their tracks through the region of space distributed hydrometeors. As a sign of the similarity of the dynamics of the adopted sequences, the increase, decrease or preservation of wavelet coefficients with the same indices unchanged are considered. To estimate the similarity of the dynamics of the received sequences from the comparison of neighbouring wavelet coefficients in the coefficient groups, one-dimensional arrays A_q and B_q are formed, where q is 1, 2 ...Q - numbering of positions. In the case of coincidence of elements of arrays A_q and B_q with the same indices, sign 1 is produced, in the case of mismatch - sign 0. The similarity of the dynamics of the received sequences is estimated by the specific weight of the number of coincidences obtained on the basis of summing the results of comparisons of the elements of the arrays A_q and B_q with the same indices.

EFFECT: simplifying the implementation of the method and eliminating the limitation of functionality in the territory with a low density of earth stations.
