Abstract :
An array signal model exploiting first-order cyclostationarity of source signals is presented, and an efficient approach to estimate the DOA utilizing the least square (LS) method is developed in this paper. For the cases of single and multiple objects, simulations are made and the results indicate the efficiency of the given method
