Matching pursuit via continuous resolution cell rejection in presence of unresolved radar targets
2015
In this article a new matching pursuit algorithm with continuous radar resolution cell rejection is proposed. It allows matching pursuit to work well even if more than one target is present in some resolution cell (unresolved targets) of the radar matched filter: it prevents its tendency to generate spurious sidelobes or miss a weaker target hidden in stronger target sidelobes. The FMCW radar case is particularly investigated which offers a very natural and computationally inexpensive solution to the problem that can also be applied in spectral analysis. The extension of the proposed approach to any radar waveform is also investigated.
