MIMO radar imaging target usually has a block sparse characteristic, Pattern-coupled sparse Bayesian algorithm can better restore block sparse signals, but its main drawback is that in each iteration involves the complex matrix inverse. Combining the pattern-coupled sparse Bayesian algorithm with the fast inverse sparse Bayesian algorithm, a pattern-coupled fast inverse sparse Bayesian algorithm is set up, which will reverse complex matrix inverse into diagonal dimensional matrix inversion, and realize the MIMO radar target quickly and accurately refactoring. Through the simulation analysis, compared with traditional algorithm, the proposed algorithm can greatly reduce the imaging time, and the realize the efficient recovery of the target.
Key words: MIMO radar imaging; pattern coupled; block sparse; fast inverse
