Radar scene generation for tactical decision aids [PDF]

The Mueller matrix and polarization covariance matrix for polarimetric radar systems was studied. The clutter was modeled by a layer of random permittivity, described by a three-dimensional correlation function, with variance, and horizontal and vertical

Trains Detection Using LTE Downlink Reference Signals

IEEE Access
In this article a method for detecting the presence of trains on tracks by analyzing the changes in the cell-specific reference symbols parameters in the downlink signal from nearby LTE base station operating in transmit diversity mode is proposed.

Maritime moving target detection and localisation technique for Global Navigation Satellite Signals‐based passive multistatic radar

IET Radar, Sonar & Navigation
This article puts forward a ship target detection and localisation technique for GNSS‐based passive multistatic radar. The approach capitalises on the large spatial diversity offered by navigation satellite constellations to provide maritime awareness ...

Passive bistatic radar based on staring radar illuminators of opportunity.

, 2018
Passive Bistatic Radar (PBR) systems use non-cooperative illuminators of opportunity to detect, localise and track targets. They have attracted considerable research interest in recent years because they can be operated and deployed at a relatively low cost, they are difficult to detect and hence allow covert operations in hostile environments, and ...
