A Coherent Method for Simulating Active and Passive Radar Sounding of the Jovian Icy Moons

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2020
The possibility to apply passive radar sounding techniques to the Jovian icy moons, making use of Jupiter’s strong decametric emissions (DAMs), has recently garnered large research interest.

A smart radar absorber based on the phase-switched screen [PDF]

open access: yes, 2005
Although conventional (i.e., passive) radar absorbers are widely used for modifying the radar cross-section (RCS) of current military platforms, such absorbers may not have adequate performance to satisfy future requirements.
