| Abstract: |
| In order to improve the direction-finding(DF) precision of interferometer, enhan
ce the ability of measuring the wideband signal and expand the working frequency
range, and realize a digital wideband DF system, this paper proposes the probab
ility phase difference ambiguity resolution model and fast algorithm based on MA
P( Maximum a Posteriori). The simulation result shows the proposed algorithm is
featured by fast resolution speed, strong resolution capability and low error re
solution probability. It can find wide application in the field where phase diff
erence ambiguity resolution is required. |
