Research of Width of Working Sector of Direct Digital Correlative-interferometric Direction Finder With Reconstruction of Spatial Analytical Signal
It was conducted the research of the width of the working sector and the exactness of direct digital correlative-interferometric direction finder that uses reconstruction of spatial analytical signal. It is shown that the main operation that has a basic effect on the width of the working sector of the direction finder is the parallel two-dimensional filtration of the radiation with using of algorithm of fast Fourier transform (FFT).
