  • Estimation of incidence angles in phased antenna arrays
    Patent number: 10299242
    Abstract: The representative embodiments discussed in the present disclosure relate to techniques in which the transmission and reception of phase array antennas may be measured to more accurately and more efficiently estimate incidence angles of the associated RF signals. More specifically, in some embodiments, RF signals may be transmitted and received by various subsets of antennas in a pair of phased antenna arrays, and the resulting signals may adaptively filtered and fed back to perform iterations until incidence angles may be accurately determined.
    Type: Grant
