  • Method and apparatus for direction finding
    Patent number: 7427954
    Abstract: A direction finding system is used in which a number of adjacent bands are sequentially measured in fast rotation, with the results from each of the bands being FFT processed to provide amplitude and phase information on all of the signals existing within the band. Upon ascertaining that one wishes to do a direction finding process, one merely accesses the information in the delay memory so that direction finding resources are only allocated to signals of interest and such that one does not have to re-do an FFT upon finding a signal of interest.
