An Intelligent Electronically Spinning TACAN Antenna

Transmit TACAN Bearing Information with a Circular Array

“…While this appears to suggest that coarse measurement is more accurate, this is somewhat illusory, as the error component due to signal noise, not included here, will generally dominate and be substantially greater for the coarse measurement than for the fine measurement. Certainly the Figure 7 numbers leave plenty of room for those noise-related errors before the TACAN system error limits of 10 ∘ and 2 ∘ for the coarse and fine readings, respectively [5], are breached. …”

“…While TACAN specifications [5] address both the static elevation pattern and the dynamic azimuth pattern, here we focus on the latter. Our design example assumes an array of Vivaldi elements characterized by embedded element patterns obtained through HFSS simulations.…”
