Radar antenna with near-field cylindrical obstruction. Computer-program description
A technique for the calculation of the radiation patterns of radar antennas with single near-field cylindrical obstructions is described. The computed and measured results are compared for a highly directional S band-radar antenna. Consideration is then given to the possible extensions of the method for cylinders of finite length and of noncircular cross-section, as well as for 3-dimensional radars.
