This paper presents a superresolution algorithm. n the Gram-Schmidtorthogonality method
analyzes the sensitivity of the direction-of-arrival (DOA) of the algorithm to the gain and phase errors
and gives the numerical results of the sensitivity related with different number of elements and different element spacing about two sources. The results show that the algorithm in this paper is more insensitive to the gain and phase errors than the Maximum Likelihood Method (MLM) and MUSIC method in condition of small seperating angle and large number of elements.
