摘要 |
A doppler navigation antenna having automatic land-sea error correction through the utilization of two somewhat differently inclined lobe groups consisting of four lobes each, and employing a plane radiator group which comprises a plurality of individual radiators arranged in parallel rows. Each end of each radiator is fed by a pair of feed lines which extend transversely in the rows, the individual feed lines of each pair of feed lines having slightly different phase delay characteristics.
