Multi-illuminator and multistatic passive radar
, 2022 S.821-850Passive radar (PR) is always dependent on illuminators of opportunity and the waveform they provide. Using multiple different illumination sources as well as the distribution of multiple sensors in multistatic networks can provide some diversity.

Unambiguous SAR Signal Reconstruction from Nonuniform Displaced Phase Center Sampling [PDF]
, 2004 The displaced phase center (DPC) technique will enable a wide-swath synthetic aperture radar (SAR) with high azimuth resolution. In a classic DPC system, the pulse repetition frequency (PRF) has to be chosen such that the SAR carrier moves just one half ...

First Coincident Radar and Optical Observations of a Meteor Radio Afterglow
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract It has been hypothesized that Meteor Radio Afterglows (MRAs) occur due to resonant transition radiation (RTR) where suprathermal electrons emit as they pass through electron density inhomogeneities in a turbulent plasma. Meteor trails are thought to produce suprathermal electrons through anion oxidation, which can be identified through meteor ...

Frequency Selective Rasorber With Low Insertion Loss and Ultra‐Broadband Scattering Reduction
Advanced Physics Research, Volume 5, Issue 2, February 2026.We present a dual‐polarization broadband frequency selective rasorber featuring a transmission window in the middle of its absorption band. The proposed FSR achieves a –10 dB reflection band over 3.68–16.94 GHz with a fractional bandwidth of 128.6%, featuring a minimum insertion loss of 0.3 dB at 10.3 GHz.
