METHOD OF DIRECTION FINDING TO RADIATION SOURCES BASED ON REFLECTION OF SUBSPACES Russian patent published in 1997 - IPC

FIELD: radio engineering, angular measurements in radar, sonar, geophysical and other location systems. SUBSTANCE: reduction of computation operations is realized thanks to evaluation of mutual covarian matrix R_xy of signals received by first and second identical antenna arrays displaced with reference to each other by distance Δ.. Bearings to radiation sources relative to normal to direction of displacement Δ are determined from non-zero generalized inherent values of matrix pair {R*xy

, R_xy}.. In this case there is no necessity in evaluation of covariance matrix of signals received by first and second antenna arrays. EFFECT: reduced number of computation operations. 1 dwg
