Direct digital method of the correlation-interferometric radio direction-finding with reconstructing of spatial analytical signal
In this paper, a new direct digital method of the correlation-interferometric radio direction-finding with reconstructing of spatial analytical signal is designed. Proposed method due to the previous parallel spatial selection of radiations separately on every their time spectral constituent and subsequent reconstructing of spatial analytical harmonic signals with the purpose of direct exact estimation of values of spatial frequencies of signals, and also use of direct dispersion-correlation processing of arrays of values of determined spatial frequencies of the reconstructed harmonic spatial analytical signals, which correspond to one direction, carries out in the real-time realization the direct estimation of directions on all radiation sources, which got in the band of frequencies of parallel analysis of radio direction finder. Thus the spectrums of signals can fully recovered on frequency.
