Abstract EN
Knowing source number correctly is the precondition for most spatial spectrum estimation methods; however, many snapshots are needed when we determine number of wideband signals.
Therefore, a new method based on Bootstrap resampling is proposed in this paper.
First, signals are divided into some nonoverlapping subbands; apply coherent signal methods (CSM) to focus them on the single frequency.
Then, fuse the eigenvalues with the corresponding eigenvectors of the focused covariance matrix.
Subsequently, use Bootstrap to construct the new resampling matrix.
Finally, the number of wideband signals can be calculated with obtained vector sequences according to clustering technique.
The method has a high probability of success under low signal to noise ratio (SNR) and small number of snapshots.
