Convergent condition and applied range extension of MAP-NSF algorithm
Wang Jiyang · Chinese Journal of Radio Science · 2001
To extend the applied range of MAP-NSF algorithm, the problem of robust estimation of DOAs of spatial signals under gain/phase error and unstructured error were considered. The parameterization relationship between gain/phase error model and unstructured error model was discussed firstly, after theoretical analysis, the convergent condition of MAP-NSF algorithm was derived under unstructured error and we extended the applied range of this algorithm under gain/phase error. The numerical results validate the theoretical analysis.
