DRFM-Based Repeater Jamming Reconstruction and Cancellation Method with Accurate Edge Detection
Remote Sensing, 2023 Digital radio frequency memory (DRFM) based repeater jamming can create false targets, which can lead to a loss of situational awareness, misidentification of targets, and decreased overall performance of the radar system. Traditional jamming suppression

Jamming I: A volume function for jammed matter [PDF]
Physica A: Statistical Mechanics and its Applications, 2010 We introduce a "Hamiltonian"-like function, called the volume function, indispensable to describe the ensemble of jammed matter such as granular materials and emulsions from a geometrical point of view. The volume function represents the available volume of each particle in the jammed systems.
