Fractional harmonic transform on point cloud manifolds
Jiamian Li, Bing-Zhao Li
Three-dimensional point clouds can be viewed as discrete samples of smooth manifolds, allowing spectral analysis using the Laplace-Beltrami operator (LBO). However, the traditional…

Anti-interrupted sampling repeater jamming via linear canonical Wigner distribution lightweight LFM detection
Jia-Mian Li, Bing-Zhao Li
Interrupted sampling repeater jamming (ISRJ) poses a serious threat to radar target detection. Traditional time-frequency (TF) domain anti-jamming methods are prone to TF aliasing…
