Abstract
Aiming at the problem that the direct location algorithm has reduced or even failed to locate coherent source directly, coherent signals dierct location algorithm based on spatial smoothing is proposed. Which adopts the idea of spatial smoothing to realize the full rank of the received source covariance matrix and adopts “Z” word spatial smoothing extends the application range of this idea from linear array to area array, and realizes the direct location of multi station coherent source by using the technology of multi station noise subspace fusion and normalization. The simulation results show that the algorithm can achieve better resolution and direct location for narrow-band coherent source under the condition of long source distance and low signal-to-noise ratio, and under the configuration of linear array and area array, it has good positioning effect.
