METHOD FOR PROCESSING SIGNALS IN MULTI-CHANNEL PHASE direction-finding radio sources shortwave

摘要

A signal processing method when the multi-channel phase DF radiation source short-range comprising frequency selection of the received signal and measuring the signal phase at each element of the antenna array, characterized in that radiation source frequency estimate of the signal phase at the geometric center of the antenna array, each element of the array is determined signal phase relative to the phase at the geometric center of the antenna array, form a matrix and the matrix coordinates of the antenna eshetki define spherical surface vector search the arrival of the plane wave, are helper vector defining the center region of possible wave vector measurement errors build a family of similar ellipsoids errors with a total found center determine the tangent point of the ellipsoid of this family of a spherical surface are signal arrival the vector and its corresponding azimuth and elevation.
