Abstract
A technology is described for direction finding. An example of the technology can include executing stages of an N stage search for a direction finding estimate of a plane wave X. The stages of the N stage search include searching a search space in a calibration set having a plurality of points in space and calculating a direction finding estimate, wherein a first search space is a coarse set of points in space and subsequent search spaces selected for subsequent stages of the N stage search are increasingly finer sets of points in the space, and a solution for the direction finding estimate output by a stage of the N stage search is used to select a next search space for a next stage of the N stage search. A direction finding estimate output by a final stage of the N stage search is the final direction finding estimate.
