Abstract
A method for locating an interferer is provided. The method includes determining, from one of a time difference of arrival (TDOA) signature and a frequency difference of arrival (FDOA) signature between a first signal received at a satellite at a first location and a second signal received at the same satellite at a second location, a first curve on which the interferer lies, determining, from direction of arrival information generated using signals received from the interferer at a plurality of elements of a linear array on the satellite, a second curve on which the interferer lies, and determining, based on an intersection between the first and second curves, the location of the interferer.
