Abstract

In order to solve the angle estimation problem of coherent sources under the non-stationary random noise background, an algorithm based on correlation vector Teoplitz reconstruction and oblique projection is proposed. First, transform non-stationary noise into Gauss white noise by correlation vector Toeplitz reconstruction. Then the oblique projection method is used to separate independent and correlated sources. Finally, the conventional algorithm is adopted to estimate the DOA and DOD of bistatic MIMO radar. The algorithm has no loss of array aperture and better angle estimation performance in the case of low signal-to-noise ratio.
