ABSTRACT:
A mono-lobed scanner used in a direction finding radar receiver has an antenna in the form of a parabolic dish having four parallel dipole antenna elements which are located physically about the parabola focal point. The outputs of the dipole elements are combined to produce a sum signal, a delta elevation signal and a delta azimuth signal. Pointing or positional inaccuracy of the antenna caused by cross polarization products is corrected by manipulation of metalic rods located about the dipoles and in relatively close proximity thereto.
