The performance of the algorithm for estimating the azimuth angle using data matrix fitting in the frequency domain

This paper shows the extension of Data matrix fitting-based Direction-of-Arrival (DOA) algorithm from the time domain to the frequency domain. We show that it is possible to implement Data matrix fitting-based DOA algorithm in the frequency domain and the estimation performance is superior to the DOA estimation algorithm in which no compressive sensing is applied to sinusoidal incident signals.
