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 θ.sub.n of an n-th antenna configuration, where n is an integer between 1 and N, and an azimuthal angle φ.sub.n 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, P.sub.n. A spherical weighted directional mean vector (X.sub.DF, Y.sub.DF, Z.sub.DF) is then estimated for the radio signal as $X_{\mathrm{DF}}=\frac{1}{N}\underset{n=1}{\overset{N}{.Math.}}{P}_n\cos \left({\varphi }_n\right)\sin \left({\theta }_n\right),Y_{\mathrm{DF}}=\frac{1}{N}\underset{}{\overset{}{.Math.}}$
