Spectral-factorisation Root-MUSIC algorithm for super-resolution ISAR imaging
The Journal of Engineering, 2019 Inverse synthetic aperture radar (ISAR) is widely used in both military and civil fields recently. The fast Fourier transformation is the conventional method to obtain high-resolution ISAR images, but it is Rayleigh limited and has high sidelobes.

Investigate and measure the angular accuracy of ML, MUSIC, Root-MUSIC algorithms and spatial smoothing in signal detection [PDF]
Fanāvarī-i āmūzish, 2007 In this paper, we first simulate ML, MUSIC, Root-MUSIC algorithms and space smoothing in noisy and fiddling environments, and then these algorithms are compared in terms of estimating the accuracy of the angles received from the two sources.
