Firstly, the authors briefly describe two models for tracking the maneuvering trajectories of non-cooperative space targets: the relative dynamics model and the indirect measurement model. In the ...

A novel two-stage Track-Before-Detect (TbD) method has been developed to significantly improve the detection of weak moving targets using reflected Global Navigation Satellite System (GNSS) signals.

An international research team has developed a hybrid maximum power point tracking (MPPT) technique for PV systems that operate under partial shading or rapidly changing atmospheric parameters. The ...
