In this research paper, we evaluate the arrangement transmitter system by Direction of Arrival (DOA) estimation plan, and on the evaluation, we make clear problems related to the hardware and transmission background of the arrangement transmitter system [1]. Arrangement transmitter systems are often modeled without any capacity and the possessions of distinction in characteristics, joint coupling, built-up mistakes, etc., are rarely deliberate. DOA estimation using an arrangement transmitter is categorized based on the principle of beam and null steering. Both methods require the steering vector of the arrangement transmitter for estimation.
