A MIMO FMCW radar approach to HFSWR [PDF]
Advances in Radio Science, 2011 In this paper we propose one possible approach how to apply the concept of multiple-input multiple-output (MIMO) to monostatic Frequency Modulated Continuous Wave (FMCW) High-Frequency Surface Wave Radar (HFSWR) in a maritime environment.

Power Quality‐Oriented Multiloop Design of Floating Wind Turbines Pitch Control
Wind Energy, Volume 29, Issue 4, April 2026.ABSTRACT Floating offshore wind turbines (FOWTs) face inherent control limitations in above‐rated operating conditions due to right‐half‐plane zeros in the blade‐pitch‐to‐rotor‐speed dynamics, which restrict achievable control bandwidth and may lead to closed‐loop instability.
