| Abstract: | A new algorithm is proposed for bearing estimation of the narrow-band near field sources in the spherical coordinates (azimuth, elevation and range), which can distinguish $2p$ independent sources with a cross array of $2p+3$ elements by exploiting the time-domain and space-domain correlations of impinging signals jointly. The number of distinguishable sources in our algorithm is more than double of that in conventional algorithms when the number of array elements is the same. In addition, our algorithm exploits the eigen values and vectors simultaneously, and then the calculated parameters only need simple pairing and the multidimensional searching can be omitted completely. Simulation results demonstrate the novelty, validity and effectiveness of the proposed algorithm. | ||
