Waveform Design in MIMO Radar Using Radial Point Interpolation Method

IEEE Communications Letters, 2018
In this letter, we consider the problem of waveform design in colocated multiple-input multiple-output radars in order to obtain a desired beampattern. In this problem, practical constraints, such as constant envelope (CE) and low peak-to-average power ratio, are very important. Therefore, we propose a simple method to generate some practical waveforms,

A LINEARLY CONFORMING RADIAL POINT INTERPOLATION METHOD FOR SOLID MECHANICS PROBLEMS

International Journal of Computational Methods, 2006
A linearly conforming radial point interpolation method (LC-RPIM) is presented for stress analysis of two-dimensional solids. In the LC-RPIM method, each field node is enclosed by a Voronoi polygon, and the displacement field function is approximated using RPIM shape functions of Kronecker delta function property created by simple interpolation using ...

The natural neighbour radial point interpolation method: dynamic applications

Engineering Computations, 2009
PurposeThe purpose of this paper is to extend the natural neighbour radial point interpolation method (NNRPIM) to the dynamic analysis (free vibrations and forced vibrations) of two‐dimensional, three‐dimensional and bending plate problems.Design/methodology/approachThe NNRPIM shape‐function construction is briefly presented, as are the dynamic ...

Dielectric boundary conditions with the meshless radial point interpolation method

2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference, 2010
A systematic approach to incorporating dielectric boundary conditions in the meshless Radial Point Interpolation Method (RPIM) is presented in this paper. In the standard RPIM method, direct implementation of dielectric interface boundary conditions has posed a technical challenge as the radial basis function used for the local interpolation of field ...

Numerical dispersion analysis of radial point interpolation meshless method

2017 Progress in Electromagnetics Research Symposium - Fall (PIERS - FALL), 2017
A general numerical dispersion relationship of the two-dimensional (2-D) radial point interpolation meshless (RPIM) method is deduced in detail in this paper. The characteristics of the numerical dispersion of the RPIM method based on Gaussian and Multiqudric basic functions are both observed.

Time‐domain vector potential technique for the meshless radial point interpolation method

International Journal for Numerical Methods in Engineering, 2015
SummaryA time‐domain meshless algorithm based on vector potentials is introduced for the analysis of transient electromagnetic fields. The proposed numerical algorithm is a modification of the radial point interpolation method, where radial basis functions are used for local interpolation of the vector potentials and their derivatives.
