Mixed targets localization using symmetric nested frequency diverse array radar
IET Signal Processing, 2021 A mixed near‐field and far‐field targets localization method based on sparse signal reconstruction and subspace method is presented, which can obtain both direction‐of‐arrival (DOA) and range information of the targets by utilizing symmetric nested ...

Symmetries, Invariants and Generating Functions: Higher-order Statistics of Biased Tracers [PDF]
, 2017 Gravitationally collapsed objects are known to be biased tracers of an underlying density contrast. Using symmetry arguments, generalised biasing schemes have recently been developed to relate the halo density contrast $\delta_h$ with the underlying ...

Image restoration using HOS and the Radon transform [PDF]
, 1993 The authors propose the use of higher-order statistics (HOS) to study the problem of image restoration. They consider images degraded by linear or zero phase blurring point spread functions (PSF) and additive Gaussian noise.
