<p>A radio wave receiving apparatus including a signal processing circuit comprising: a means (6-1) for the Fourier transform in respect of azimuth of an electric field signal outputted from an antenna receiving circuit; a means (6-2) for the Fourier transform in respect of azimuth of the antenna pattern of an antenna; a means (6-3) for dividing the Fourier transform signal resulting from the electric field signal by the antenna pattern Fourier transform signal; and a means (6-4,6-5) for passing the divided signal through a low-pass filter in respect of azimuthal frequency and then subjecting it to a Fourier inverse transform in respect of azimuth, so as to output the signal after the Fourier inverse transform as a final antenna output, thereby improving the antenna resolution by using a transfer function in the azimuthal frequency domain resulting from the Fourier transform of the antenna pattern in respect of azimuth. <IMAGE> <IMAGE></p> |
