Abstract: DOA computation is a major issues in several applications. This kinds of application found in remote wireless communication system, radar system, radio astronomy system, sonar system and navigation system. Determination of a DOA computation will be improved using a antenna arrangement by an advanced signal processing procedure techniques. These DOA techniques have improved array antenna arrangements to process various receiving signals at array elements. These methods possess good capability to find a DOA of various sources. This work can elaborate implementation of DOA computation algorithmsMUSIC &ESPRIT based on a ULA in existence of various environmental noises. Execution of DOA mainly depends on various input parameters like snapshots, No.of array sensors, SNR ratio. Simulation results found shows MUSIC & ESPRIT performance can be increased efficiently as no. of snapshot, no. of array components, SNR& angle between 2 target sources are enhanced.
