Multistatic Cloud Radar Systems: Joint Sensing and Communication Design

, 2016
In a multistatic cloud radar system, receive sensors measure signals sent by a transmit element and reflected from a target and possibly clutter, in the presence of interference and noise.

The Case for Combining a Large Low-Band Very High Frequency Transmitter With Multiple Receiving Arrays for Geospace Research: A Geospace Radar [PDF]

, 2019
We argue that combining a high‐power, large‐aperture radar transmitter with several large‐aperture receiving arrays to make a geospace radar—a radar capable of probing near‐Earth space from the upper troposphere through to the solar corona—would ...

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 ...

Multistatic acoustic characterization of seabed targets [PDF]

The Journal of the Acoustical Society of America, 2017
One application for autonomous underwater vehicles (AUVs) is detecting and classifying hazardous objects on the seabed. An acoustic approach to this problem has been studied in which an acoustic source insonifies seabed target while receiving AUVs with passive sensing payloads discriminate targets based on features of the three dimensional scattered ...

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.

Uncoupled Digital Radars Creating a Coherent Sensor Network

IEEE Journal of Microwaves
Radar networks offer the possibility to overcome the limitations of single sensors. However, without coherent signal processing, the full potential of radar networks cannot be exploited.
