METHOD DETERMINING ANGULAR COORDINATES OF GRAVITATION- WAVE SOURCE Russian patent published in 2001 - IPC

FIELD: determination of angular coordinates of gravitation-wave sources. SUBSTANCE: N cycles of coherent accumulation of detected gravitationwave signal are conducted during annular orbital rotation of the Earth at unspecified fixed time moment in sequence. Detected gravitation-wave signal is extracted in each of N cycles with account of motion of the Earth by way of its coherent accumulation in n periods and phase of accumulated gravitation-wave signal in each N-th cycle is memorized. Measurement of difference between accumulated gravitation-wave signals is repeated M times at following positions of gravitation-wave detector during orbital motion of the Earth and angular position of gravitation-wave source relative to same Earth traveling in plane of orbital motion and occupying M positions in this plane is found M times. Angular coordinates of source of detected gravitation-wave signal relative to plane of ecliptic and point of vernal equinox are calculated by all values of angular position of gravitation-wave source determined during annular orbital movement of gravitation-wave detector. EFFECT: improved accuracy of determination of angular coordinates of signal source in long-wave range of gravitational radiation. 1 dwg
