| 摘要 | High precision radio frequency direction finding systems are described that can determine an angle-of-arrival and geo-location of a RF emitter with respect to a mobile platform. A radio frequency direction finding (RFDF) system for determining a position of a RF emitter with respect to a mobile platform can include an angle-of-azimuth (AoA) system configured to determine an azimuth of a RF emitter with respect to the mobile platform; an attitude measurement system configured to measure the attitude of the mobile platform; a geo-location system configured to calculate the geo-location of the RF emitter; and a processor system configured to calculate a position of the RF emitter. | ||

| 主权项 | 1. A radio frequency direction finding (RFDF) system for determining a position of a RF emitter with respect to a mobile platform, the system comprising: an angle-of-azimuth (AoA) system configured to determine an azimuth of a RF emitter with respect to the mobile platform, wherein the AoA system comprises a RF interferometer; an attitude measurement system configured to measure the attitude of the mobile platform; a geo-location system configured to calculate the geo-location of the RF emitter; a processor system configured to calculate a position of the RF emitter; and an alignment system configured to align the RF interferometer. | ||
