Witryna1 gru 2024 · Similar to the Newtonalized orthogonal matching pursuit (NOMP) for line spectral estimation problem, the NOMP for the FAR radar termed as NOMP-FAR is designed to process each coarse range bin to ... WitrynaOrthogonal matching pursuit (OMP) is an efficiently iterative greedy algorithm, which chooses the column of observation matrix that is most correlated to the current residual at each step. Unfortunately, as an on-grid compressed sensing (CS) method, the OMP suffers from the grid-mismatch effect. ...

We find a simple regularized version of Orthogonal Matching Pursuit (ROMP) which has advantages of both …
Witryna29 lis 2011 · As a greedy algorithm to recover sparse signals from compressed measurements, orthogonal matching pursuit (OMP) algorithm has received much attention in recent years. In this paper, we introduce an extension of the OMP for pursuing efficiency in reconstructing sparse signals. Our approach, henceforth …
Witrynapursuit algorithms (e.g., OMP and Matching Pursuit). We do not require explicit estimates of model order, and provide a stopping criterion based on CFAR (constant false alarm rate) based on an estimate of the noise variance. (2) We prove convergence of NOMP by providing upper bounds on the number of iterations. Moreover, we derive a Witryna9 wrz 2024 · This paper proposes a two-dimensional Newtonized orthogonal matching pursuit compressive beamforming, including single and multiple snapshot versions, which constructs the maximum likelihood estimation model, taking the position and strength of sources on a two-dimensional continuous plane as parameters.
