Abstract

See full text

The reconfigurable radio direction finder system and method uses a reconfigurable antenna to electronically cycle through a plurality of different antenna configurations to determine a signal direction. Specifically, the reconfigurable antenna is cycled through N different antenna configurations, where N is an integer greater than one, where each antenna configuration has a pointing direction associated therewith defined by an elevation angle θn of an n-th antenna configuration, where n is an integer between 1 and N, and an azimuthal angle φn of the n-th antenna configuration. A received signal strength of the radio signal is measured for each of the antenna configurations as a power output of the n-th antenna configuration, Pn. A spherical weighted directional mean vector (XDF, YDF, ZDF) is then estimated for the radio signal as
