Summary:
In the estimation of the direction of arrival (DOA) of radio waves using FOCUSS, the improvement effect of a method introducing FFT as a pre-processing step (FFT-FOCUSS) has been confirmed. In this paper, we attempt a performance analysis of FFT-FOCUSS in DOA estimation of the first arrival wave in a multipath environment using multiple thinned arrays. the median filtering of DOA estimates from the multiple thinned arrays improves the estimation accuracy of the first arrival wave in a multipath environment.
