Abstract :
The effects of amplitude and phase errors are determined for symmetric and asymmetric linear predictive array processors. The maximum entropy method (MEM) corresponds to linear prediction in the asymmetric case of a line array of equispaced elements with an end reference. A comparison to conventional beamforming and maximum-likelihood processing shows that they have the same peak location as the symmetric linear predictive array processor
