A Multi-Objective Quantum Genetic Algorithm for MIMO Radar Waveform Design

Remote Sensing, 2022
Aiming at maximizing waveform diversity gain when designing a phase-coded multiple-input multiple-output (MIMO) radar waveform set, it is desirable that all waveforms are orthogonal to each other.

Mathematical model of spatial and temporal processing of broadband signals in satellite radio systems of broadband access and radio navigation

Космические аппараты и технологии, 2023
To effectively receive a useful broadband signal, it is necessary to compensate for distortions caused by the complex frequency-dependent coefficient of the receiving and transmitting antenna, multiplicative interference and noise from the heterogeneity ...

Microstructural degeneracy associated with a two-point correlation function and its information content. [PDF]

Physical review. E, Statistical, nonlinear, and soft matter physics, 2012
A two-point correlation function provides a crucial yet an incomplete characterization of a microstructure because distinctly different microstructures may have the same correlation function. In an earlier Letter [Gommes, Jiao, and Torquato, Phys.

Power spectral models of stationary earthquake-induced ground motion process considering site characteristics

Emergency Management Science and Technology, 2022
In this article, several spectral models describing the stationary stochastic process of earthquake ground motion are explored and compared. The Hu-Zhou spectrum, which is regarded as an improved model of the Kanai-Tajimi spectrum, is concerned.

Large-scale 3D galaxy correlation function and non-Gaussianity [PDF]

, 2013
We investigate the properties of the 2-point galaxy correlation function at very large scales, including all geometric and local relativistic effects --- wide-angle effects, redshift space distortions, Doppler terms and Sachs-Wolfe type terms in the ...

The Off-forward Quark-Quark Correlation Function [PDF]

, 2006
The properties of the non-forward quark-quark correlation function are examined. We derive constraints on the correlation function from the transformation properties of the fundamental fields of QCD occurring in its definition.

Density of States for a specified correlation function and the energy landscape. [PDF]

Physical Review Letters, 2012
The degeneracy of two-phase disordered microstructures consistent with a specified correlation function is analyzed by mapping it to a ground-state degeneracy.
