| Abstract: | This paper presents an analysis of the effect of the amplitude and phase perturbation (modeling error) on the performance of the MUSIC algorithm.The theorectical expression of the statistical spatial spectrum for the case of modeling error existing in the system is derived.The theoretical analysis reveals the relationship between the error of spectrum and the variance of perturbation.The theoretical prediction is validated by computer simulating.The amplitude and phase perturbation decrease the peak values of spectrum and lower the resolution power.The results are of great significance to the array designer. |
