DOA estimation of desired signals using radio holography and signal cyclostationarity

The radio holography method performs the direction-of-arrival (DOA) estimation of radio waves with a relatively simple array system because it uses a reference antenna. This paper proposes a new radio holography method in which cyclic correlations of digital-modulation signals are introduced for the DOA estimation of desired signals only. The DOA estimation accuracy of the method is evaluated by computer simulation and the effectiveness of the method is shown.
