Abstract

The authors present a method for the analytical evaluation of the radiation patterns of a TACAN (tactical air navigation) antenna, based on image theory. The discone antenna utilized in TACAN gives an omni pattern in the horizontal plane. A single lobe caused by the inner parasitic and nine lobes arising due to the outer parasitics together effectively enable coarse and fine bearing measurements. Since the inner and outer parasitics are both rotated at 15 rev/s, the nine-lobed pattern rotates in space at a 15-Hz rate
