Forward scatter radar for air surveillance: Characterizing the target-receiver transition from far-field to near-field regions [PDF]
, 2017 A generalized electromagnetic model is presented in order to predict the response of forward scatter radar (FSR) systems for air-target surveillance applications in both far-field and near-field conditions.

Analysis of Bistatic Ground Clutter and Applications to Target Plotting [PDF]
Radioengineering, 2018 This article presents analysis and parametrization of the bistatic ground clutter which is important from the point of view of the modelling/generating of bistatic clutter, and subsequent developing of the new suppression techniques.

Using Particle Filter for Estimating Velocity of Maneuvering Target Being Tracked by Passive Radar
Syrian Journal for Science and InnovationTracking a target is achieved by estimating its range and velocity, and this process has two types: Bistatic Tracking and Cartesian Tracking. In a passive radar system, the bistatic tracking is achieved by processing the bistatic geometry “One non ...

Near-Space Microwave Radar Remote Sensing: Potentials and Challenge Analysis
Remote Sensing, 2010 Near-space, defined as the region between 20 km and 100 km, offers many new capabilities that are not accessible to low earth orbit (LEO) satellites and airplanes, because it is above storm and not constrained by either the orbital mechanics of ...

Neural Network–Assisted Metasurface Retroreflector With Wide‐Angle Adaptivity
Electron, EarlyView.This work proposes a wide‐angle, multi‐polarization, self‐sensing, and self‐adaptive intelligent metasurface retroreflector, with a planar profile and ultrathin thickness. By integrating a pre‐trained artificial neural network (ANN), the metasurface retroreflector can recognize the incident angle and promptly adapt to changes in the incoming wave.
