ABSTRACT:
Disclosed is an Radio Frequency (RF) volumetric direction finding (DF) methodology, utilizing an Half Maxwell Fish-eye (HMFE) Lens having a semi-spherical shape, a focal plane with a feed structure composed of near-equally spaced frequency-independent antenna elements disposed uniformly to form a 2-dimentional feed array; and RF power splitters for each element and combiners for combining the RF energy received by the elements; forming rows and columns; thereby reducing the number of required RF receiver channels for subsequent processing, where the maximum row/column and differential amplitude comparison is used for deriving DF estimation of intercepted signals; as part of a robust signal detection and direction-finding (DF) system; for detecting and processing a plurality of signals emanating from navigation, radar and communication equipment on surface and airborne platforms.
