This paper proposes an approach to study the effect of faulty array element on the accuracy of the parameter estimation of direction of arrival of the plain waves and their amplitudes from sources that are considered to be far field sources. In this approach we require only one snapshot. The cost function is developed for heuristic computation using genetic algorithm (GA). Cost function is based on  norm of the difference between actual observation vector and the constructed vector plus the correlation between the two normalized vectors. The results have been given for different length of array i.e. 10, 15 and 20.Longer array is able to minimize the effect of faulty array element.
