Abstract

In order to obtain directions of arrival (DOA) of two wide-band sources effectively, with a small size four-element planar cross array, the beam-space coherent signal-subspace method (BSCSM) applied to the orientation of wide-band sources was studied, and its performance was analyzed. Measured helicopter noise was used to simulate output of array elements as wide-band sources, which contains the certain directions of target arrival. The BSCSM and CSM (coherent signal-subspace method) were employed respectively to estimate sources’ DOAs. The performance of BSCSM was compared with CSM using computer simulation. The simulation results show that BSCSM provides a better performance than CSM in the passive acoustic direction estimate for two far-field wide-band sources with small size four-element planar cross array.
