Nanophotonics, Volume 15, Issue 17, 11 September 2026.We demonstrate a VO2‐based transmissive reconfigurable intelligent surface for indoor millimeter‐wave communication. The TRIS replaces conventional PIN and varactor diodes with geometrically tailored VO2 switches, enabling transmitted phase control through phase‐transition‐based switching.

An investigation of bistatic calibration techniques [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2005 Several popular bistatic calibration techniques are investigated and comparisons made between the relative merits of the various techniques. The analysis addresses sensitivity to object alignment error, sensitivity to polarization impurity, and ease of implementation.

DETECTION OF MULTIPLE TARGETS BY A MULTISTATIC RADAR
Perner’s Contacts, 2009 Multistatic radar systems with several transmitters and receivers introduce not only new qualities in area surveillance as well as in hardware minimization but also new problems in signal processing and target detection and tracking.

A Multiple Interference Suppression Algorithm Based on Airborne Bistatic Polarization Radar
Leida xuebao, 2022 To solve the problem of the simultaneous suppression of main-lobe and side-lobe interferences, this study applies polarization information as input to the airborne bistatic radar and constructs an airborne bistatic polarization-sensitive array.

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract We introduce a data archive containing the first highly resolved profiles of velocity and sediment concentration within the wave bottom boundary layer (WBBL) on a natural sandy beach. Resolution of the thin WBBL was made possible by deployment of a unique “Multi‐Frequency Doppler” (MFDop) bistatic acoustic profiling instrument on an Oregon ...

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow
Water Resources Research, Volume 62, Issue 9, September 2026.Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Beyond SMAP: Can GNSS‐R Platforms Ensure Continuity of Global Soil Moisture Observations?
Water Resources Research, Volume 62, Issue 9, September 2026.Abstract The absence of a definitive follow‐on strategy for the Soil Moisture Active Passive (SMAP) mission, which has already surpassed its planned mission lifetime, presents a significant challenge for the hydrological science community. GNSS‐Reflectometry (GNSS‐R), which exploits reflected satellite navigation signals, has emerged as a rapidly ...

General Processing Approach for Bistatic SAR Systems: Description and Performance Analysis [PDF]
, 2010 For its intrinsic properties, bistatic SAR processing cannot be approached in the same manner monostatic SAR process- ing is approached. In general, a bistatic SAR processor is more than a powerful focussing algorithm.
