A novel methodology is implemented for detection of coherent signals in direction of arrival estimation of linear arrays. The available techniques for DoA estimation of incoherent signal is modified by introducing spatial smoothing technique. This spatial smoothing technique is further used to de-correlate the signals before applying MUSIC algorithm for DoA estimation. DoA estimation is also performed using ESPRIT algorithm for linear array and Performance of MUSIC and ESPRIT algorithms is compared on basis of Computational time required and resolution of DoA estimated. ESPRIT is found to be a better choice than MUSIC for DoA estimation.
