Embodiment Construction
[0017] The technical solutions of the present application will be clearly and completely described below in conjunction with the accompanying drawings and the embodiments of the present application.
[0018] figure 1 It is a flow chart of passive direction finding algorithm based on phased array selection baseline. The invention proposes to select part of the array elements in the phased array to form a two-dimensional interferometer for direction finding, and then use the interferometer direction finding results as a basis to determine the range of MUSIC space search, which can greatly reduce the MUSIC spatial spectrum while improving the direction finding accuracy. Estimated computational load, and speed up the speed of direction finding, improve the real-time performance of direction finding.
[0019] The specific steps of the passive direction finding algorithm based on phased array selection of baselines are as follows: select 6 array elements in a 5×5 phased array to fo...
