Practical aspects of the direction finding accuracy of compact wideband arrays for V/UHF frequencies

Abstract

The paper discusses some advanced topics of direction finding (DF) of communication signals and respective antenna arrays in the frequency range from 20 to 3000 MHz. There are a number of issues contributing to potentially severe performance degradation of an installed system in its typical operational environment compared to the same system operated under the well-defined test conditions on an antenna test site. It is shown that especially polarization aspects deserve more attention than traditionally paid.
