US 2025/0334661 A1 · SYSTEM AND METHOD FOR DETERMINING DIRECTION OF A RADIO FREQUENCY SIGNAL

Abstract

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 via a plurality of phased array antennas. The received RF signals may be converted 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 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 on a user device to indicate the direction of the strongest received RF signal.
