2D-DOA Estimation Based on MSCS of Multi-FH Signal
A two dimensional direction of arrival (2D-DOA) estimation algorithm based on MSCS is proposed by using space-time-frequency analyzing method. Firstly, the spatial time-frequency (TF) matrix of each hop is constructed by using the time-frequency domain features of FH signals; Then the dimension of the noise subspace is descended by the singular value decomposition on the intersection of noise subspace and its conjugate one; Finally efficient DOA estimation is realized through half-spectrum searching. Theoretical analysis and simulation results show that this algorithm has good effectiveness and estimation performance.
