Abstract:

A two-dimensional correlation interferometer algorithm based on dimension separation is proposed for wideband direction finding. The original two-dimensional angle searching is divided into 2 one-dimensional searching processes in the proposed algorithm. Therefore, the computational complexity is reduced. Meanwhile the introduced interpolation process ensures the direction finding precision. Simulation results demonstrate that compared with conventional correlation interferometer algorithm, the proposed one can offer higher direction finding speed.
