Sparse Representation Denoising for Radar High Resolution Range Profiling [PDF]

International Journal of Antennas and Propagation, 2014
Radar high resolution range profile has attracted considerable attention in radar automatic target recognition. In practice, radar return is usually contaminated by noise, which results in profile distortion and recognition performance degradation. To deal with this problem, in this paper, a novel denoising method based on sparse representation is ...

Eigenvalue‐based ground target detection in high‐resolution range profiles [PDF]

IET Radar, Sonar & Navigation, 2020
In this study, the authors address the problem of range‐distributed target detection in sequential high resolution range profiles (HRRPs). They propose a modified scaled largest eigenvalue detector for static target in homogenous ground clutter. A set of secondary data, which are free of target signal and have the same distribution as the clutter in ...
