A new algorithm using modified propagator for two-dimensional (2D) central DOA estimation of coherently distributed (CD) noncircular (NC) sources impinging on the L-shaped array structured by two uniform linear arrays (ULAs) is proposed. Without the computationally intensive and time-consuming estimation of sample covariance matrix and eigendecomposition process, the proposed algorithm estimates the...
In most research of PN code acquisition performance of antenna array, the signal DOA is regarded as a constant. But in practice, the signal DOA always spreads to a certain extent, which affects PN code acquisition performance. In this paper, the angle extension is introduced into the direct-sequence spread-spectrum array signal model, and PN code acquisition performance is analyzed through CFAR algorithm...
