One or more embodiments of the present disclosure relate to a system and method for determining direction of a radio frequency. RF signals from multiple directions may be received (404) via a plurality of phased array antennas. The received RF signals may be converted (406) into in-phase (I) and quadrature (Q) representations. The IQ representations may be decoded to extract signal characteristics. Magnitude data and phase data may be computed from the extracted signal characteristics. Signal direction vector of strongest received signal may be determined (414) by identifying peak signal strength patterns using the computed magnitude data and phase-aligned signal characteristics data. The computed signal direction vector may be rendered (416) on a user device to indicate the direction of the strongest received RF signal.
