Novel method for super-resolution in radar range domain

A method based on adaptive regularisation for range super-resolution is presented. The method is computationally efficient and has low SNR threshold close to that of the maximum likelihood (ML) method. The method can simultaneously estimate the number and time delays of the overlapping echoes, whereas determining the number of echoes in ML-type algorithms is difficult. Numerical simulation results demonstrate the performance and show that the method is capable of simply and effectively achieving enhanced range resolution
