1. A method for determining location of a radar target, said method comprising:

  • determining an interferometric angle, Φ

    , to the radar target based on at least one radar return;

    filtering the interferometric angle, Φ

    , said filtering adjusting an effect of terrain features contributing to the interferometric angle, Φ

    , proportionally to a degree of radar return fading resulting from the terrain features of the radar target; and

    providing a corrected interferometric angle, Φ

    out., based at least in part on said filtering.
