Robust array interpolation using second-order cone programming

IEEE Signal Processing Letters, 2002
We study Friedlander's (1993) array interpolation technique, whose main shortcoming in multisource scenarios is that it does not provide sufficient robustness against sources arriving outside specified interpolation sectors. In this letter, we develop a new robust interpolation approach by minimizing the interpolation error inside the sectors of ...

Optimum Beamforming Based on Second Order Cone Programming

2008 Congress on Image and Signal Processing, 2008
An approach based on second order cone programming (SOCP) is proposed to the optimum beamforming of non-uniform linear array (NULA). The approach designs the optimum beamforming according to control sidelobe and improves the problem that the Chebychev methods can only be used in the optimum beamforming of uniform linear array(ULA).

Inextensible Non-Rigid Structure-from-Motion by Second-Order Cone Programming

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2018
We present a global and convex formulation for the template-less 3D reconstruction of a deforming object with the perspective camera. We show for the first time how to construct a Second-Order Cone Programming (SOCP) problem for Non-Rigid Structure-from ...

Geotechnical localization analysis based on Cosserat continuum theory and second-order cone programming optimized finite element method

Computers and geotechnics, 2019
Based on the Hellinger-Reissner mixed variational principle, a second-order cone programming optimized finite element method for elastic and elastoplastic analyses of Cosserat continuum (named CosFEM-SOCP) is proposed.

Embedded second-order cone programming with radar applications

2015 IEEE High Performance Extreme Computing Conference (HPEC), 2015
Second-order cone programming (SOCP) is required for the solution of underdetermined systems of linear equations with complex coefficients, subject to the minimization of a convex objective function. This type of computational problem appears in compressed radar sensing, where the goal is to reconstruct a sparse image in a generalized space of phase ...

Spiral-diving trajectory optimization for hypersonic vehicles by second-order cone programming

, 2019
Spiral maneuvering targets are well known to be very difficult to intercept due to its high maneuverability and unpredictability. This paper focuses on the optimization of a spiral-diving trajectory for a hypersonic vehicle to strike a stationary target.

Visual motion estimation via second order cone programming

Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101), 2002
The visual motion, induced by ego-motion of the camera, can be estimated through resection, intersection and transfer processes. Under the assumption of affine camera, the intersection/transfer process can be formulated as a system of 5 linear equations, so that any correspondence of an image point and its affine coordinates can be obtained by solving ...
