Detection of Low RCS Unmanned Air Systems Using K-Band Continuous Wave Doppler Radar
Journal of Electrical and Computer Engineering, 2023 UASs (Unmanned Air Systems) are universally used in many activities, spanning from leisure-commercial to military applications. Accordingly, as the number of UASs operating in the sky increases, so does the need to detect and identify them, in order to ...

Optical Fiber Systems Are Convectively Unstable [PDF]
Physical Review Letters, 2008 We theoretically and experimentally evidence that fiber systems are convective systems since their nonlocal inherent properties, such as the dispersion and Raman effects, break the reflection symmetry. Theoretical analysis and numerical simulations carried out for a fiber ring cavity demonstrate that the third-order dispersion term leads to the ...

Generation and manipulation of squeezed states of light in optical networks for quantum communication and computation [PDF]
, 2001 We analyze a fiber-optic component which could find multiple uses in novel information-processing systems utilizing squeezed states of light. Our approach is based on the phenomenon of photon-number squeezing of soliton noise after the soliton has ...
